    Abstract This study aims to develop methods for minimizing underwater noise generated by impact pile driving, with a specific emphasis on pile designs less prone to producing such noise. The underwater noise originates from the expansion of the pile due to the Poisson effect as the longitudinal wave propagates through the pile while driving. It was hypothesized that an irregular surface profile of the pile could effectively induce longitudinal wave diffraction and attenuation. Both experimental trials and numerical simulations were conducted to explore how the surface profile of the pile influences underwater noise. During the experiments, driving simulations were performed using test rods, and comparisons were drawn between configurations with and without convex sections. Visual observations revealed the occurrence of oblique shock waves immediately following impact, along with arc-shaped compression waves emanating from the convex sections of the shape, subsequently leading to the formation of bubbles, thus producing compression waves. Simulation findings demonstrated that thicker test rods exhibit greater damping effects, aligning with the experimental outcomes. In the presence of convex sections, the pressure decayed more rapidly, with the pressure value after decay also being smaller compared to conditions lacking convex sections. In conclusion, it is proposed that the shape of the pile could effectively mitigate pressure waves, leading to a significant reduction in underwater noise by generating expansion waves that counteract compressive waves.

    The Deepwater Horizon accident discharged a staggering amount of oil (about 780,000 kL) into the Gulf of Mexico. In other forecast simulations based on the ocean-only models, spilled oil reached the Atlantic Ocean via the Gulf Stream. In this study, the authors simulated 3-dimensional movement of oils using real-time oceanic and atmospheric conditions obtained by the coupled MSSG (Multi-Scale Simulator for the Geoenvironment) model. Our simulation shows that the amount of oil discharge into the Atlantic is very limited due to the trade winds. The atmospheric coupling to the ocean model is essential in the forecast simulation of spilled oils.

    This paper reports the study on behavior phenomenon of shock waves in water sealed with an aluminum container numerically and experimentally. In the numerical study, the propagation of shock waves in the container is calculated by LS-DYNA using the Johnson-Cook model and the Tait equation. We observe the propagation phenomena of shock waves generated in water part of the container by elastic-plastic deformation of aluminum using the schlieren method.

    The present study reports the theoretical and experimental research of the state in a shock wave front in aluminum. Fundamental equations are derived from thermodynamic theory for the steady flow involving viscosity and heat conduction. The states in a shock wave front, such as temperature, equilibrium stress and viscous stress distributions, are calculated using the equations. The effects are investigated of viscosity and heat conduction in shock front formation. In order to consider the relation between viscous stress and strain rate in a shock front the theoretical results are compared with the experimental data obtained by VISAR (Velocity Interferometer System for Any Reflector). These results make the useful information for analysis of the structure of shock fronts to build the new hybrid wave code using the present theoretical solutions.

    In the present study we carry out the gas gun experiment and the numerical simulation to investigate the lethal effect of shock waves to a marine microorganism and behavior of waves in target containers. The marine Vibrio sp. that is isolated from ship's ballast water is used. After the impact, Vibrio sp. is cultivated for 24 hours at 30 degrees. The shock pressure effect is judged by the number of colony in agar plates. The pressure in a container is measured by the piezo-electric film gauge. We can get 2.5 kbars shock pressure in a small type container and realize 99.99% of lethal rate. On the other hand, the pressure propagation phenomena in the container are calculated by the LS-DYNA. From the comparison between experimental result and numerical one we examine the generation process of high pressure in the container.

    The present study reports the experimental research of particle velocity increasing process generated by elastic-plastic shock waves in 6061-T6 aluminum. Planar impact experiments are carried out by a single-stage light-gas gun. The gun has 2 m long launch tube and 40 mm muzzle diameter. Projectiles are made of ABS material, and accelerated by high-pressure gas (He). Impact velocities measured by the magnet flyer method are from 227 to 413 m/sec. A target plate is hold in a target ring with 4 tilt-pins. Tilt angles obtained by any shots are from 2.4 to 3.6 mrad. The velocity changes at the rear surface of target plate are measured by the velocity interferometer system (VISAR). High-resolution data focused in the plastic shock wave are obtained, and it is shown that those data can be compared to the results of estimating simulation of the shock wave profiles.

    In the present study, improvement of numerical simulation code for the prediction of shock wave rise times developed by Swegle and Grady is carried out using equilibrium (thermoelastic) stress. The thermoelastic stress is obtained from Inside Temperature (IT) method for estimating temperatures in steady shock wave fronts established by Sano and Abe. In addition, use of the artificial viscous stress is limited conditionally in order to examine effects of the real shock viscous stress in our numerical calculation. The results of our improved simulation for 6061-T6 Al shocked below 9 GPa are compared with experimental results, and obtained good agreements. While, the effect of the viscous stress determined from the thermoelastic stress in the present method shows little differences from the Swegle-Grady method.

    Heat wave in elastic material generated by an impulsive heating of the free surface is analyzed numerically in order to clarify the mechanism of a rapid alloying technology. The TVD finite difference scheme is applied for the present study to catch the discontinuous thermal waves clearly. The present numerical scheme is justificable from the results of behavior of heat waves propagated through Al metal. In addition, the propagation of heat wave through a contact boundary between two different metals, Al and Ni, is examined. The numerical results suggest that the possibility of direct contribution of heat wave to the most part of Al-Ni alloy is denied, but complicated variations of temperature are occurred at the interface. These results indicate that analyses including a phase transition phenomenon are required.

    In the Previous study, two Inside Temperature (IT-a and IT-b) methods for estimating the temperature distributions in steady wave fronts in a thermo-viscous material were established and the IT-b method was shown qualitatively to be effective if the effect of viscosity was distinguished. In this paper, these two methods are applied to the shock compressions of Yittria-doped Tetragonal Zirconia (YTZ) that is a thermo-viscous material with a multiple shock Hugoniot. The YTZ Hugoniot consists of three partial curves including two kinks, that are the Hugoniot Elastic Limit (HEL)and the phase transition point. The shock temperatures evaluated by the IT-b method were close to the accurate temperatures obtained by the Shock-Temperature method in the whole stress range to 140 GPa examined here. Furthermore, the inside temperature distributions were approximately accurate because the effect of viscosity was distinguished in the shock compression. By these facts, it was considered that the fundamental assumption and the assumption on heat transport used in the IT-b method were valid and as a result, this method was effective. In addition, the influences of heat transport on the temperatures and thermo-elastic stresses were examined.

    Two methods (IT-a and IT-b methods) for estimating temperatures in steady wave fronts in a thermo-viscous material are established. To this end, two irreversible thermodynamic equations for the temperature in the wave front are derived under the fundamental assumption that the material in the wave front is approximately in an equilibrium state. In addition, heat transport is neglected in the IT-a method, while in the IT-b method, the work done by the thermal stress is offset by heat transport. The two equations are connected with the Hugoniot function and the Mie-Gruneisen equation, respectively. The efficacy of the two methods is examined qualitatively by three temperature distributions estimated qualitatively using three equations for entropy which include no assumption on heat transport, the assumption used in the IT-a method, and that in the IT-b method, respectively. These three distributions suggest that the temperatures are overestimated by the IT-a method, while the IT-b method is effective if the effect of viscosity is distinguished.

    Heat wave in elastic material generated by an impulsive heating of the free surface is analyzed numerically by the TVD finite difference scheme. The thermal response of Al metal for a thermal shock is examined through behavior of heat wave. In addition, the propagation of heat wave through a contact boundary between two different metals, Al and Ni, is examined. The numerical results suggest that heat wave plays an important role in an initiation of Ni-Al alloying by an electric resistance welding technique.

    Wavy interface generation is an interesting characteristic of explosive welding. There have been many theoretical and experimental discussions of the mechanism of wavy interface generation, but there is no consensus of opinion as yet. We report a numerical approach to the analysis of the mechanism of interface wave generation in explosive welding. The phenomena of the interface wave generation are calculated using a two-dimensional finite difference scheme for elastic-plastic materials. In this simulation the equations for a symmetric collision between copper plates are solved. The concept behind this study is that the wavy interface and vortex streets are caused by the velocity distribution of shear flow and periodic disturbances at the interface. The calculation results show the deformation process of the wavy interface and we obtain qualitative agreements between numerical and experimental results.

One of the examples is a shock wave discharged from the open end of a square cross sectional shock tube. The experiments were conducted in 40mm×40mm cross sectional shock tube. Double exposure diffuse holographic interferometry was used for the flow visualization. The three dimensional shock configulation and the three dimensional flow behind the shock wave can be clearly observed. Other three dimensional observations in shock tube flows are also shown.

    The present paper reports a visualization study and a numerical simulation of the shock wave discharged from the open end of a shock tube. The three-dimensional shock wave flow is quantitatively visualized using double exposure holographic interferometry. In order to obtain the three-dimensional isopycnics behind the shock wave, a data evaluation process was described. The TVD finite difference scheme was applied to this problem. The experimental result was compared with the numerical result. A good agreement was obtained between them. The micro point explosions were conducted to verify the assumption of the present method that the collimated light was scarcely deviated at spherical shock fronts.

    The present paper reports the visualization study of the initiation of a shock wave generated by a rebounding bubble and a micro-jet induced when the bubble is collapsed. The underwater spherical shock wave is obtained by using a 10 mg silver azide(AgN3) pellet, and visualized by using double exposure holographic interferometry. In order to understand the quantitative properties of this phenomenon, the density and pressure distributions were evaluated by measuring the interference fringes and using Tait equation. Consequently, the sudden pressure change when the shock wave is generated by the rebounding bubble and the structure of the micro-jet were clarified

     The present paper reports on the development of a new technique of marine bacteria sterilization of ship ballast water using underwater shock waves. The interactions between microbubbles and shock waves are utilized in the proposed technique. The contraction and expansion motion of microbubbles provide biochemical and mechanical sterilization effects by means of free radicals and shock wave pressures. Theoretical and experimental approaches to the development of the present technique are described. The examination of optimum conditions for higher rebound-pressure generation from microbubbles, the observation and pressure measurements in the interaction field between microbubbles and shock waves, the performance of a unique shock wave generator and the bio-experiments with the present technique are featured in this paper.

    This paper reports the experimental study on behavior and collapse of micro-nano bubbles to develop a new ballast water treatment technology. The experimental flow system is composed of flow channels, a cooler tank, a pump, a micro-nano bubble generator, and an ultrasonic wave generator. The inactivation effect of marine bacteria of this system is checked by the colony counting method. The effect is related with the collapse of micro-nano bubbles by ultrasonic waves. The schlieren method is carried out to observe the collapse phenomena of micro-nano bubbles in the flow channel. As a result, shock waves are observed around bubbles, and it is found that the collapse of bubbles contribute to the inactivation of the marine bacteria.

    The present paper reports experimental measurements of particle velocity change at elastic-plastic shock wave fronts to estimate a hybrid numerical prediction method of particle velocity variation with shock wave propagation in metals. The elastic and plastic shock waves are generated in 6061-T6 aluminum by planer impact experiments using a single-stage light-gas gun that has 40mm muzzle diameter. Impact angles are also checked on using 4-pin-sensor system, and the particle velocity variations at the rear surface of target plates are measured by a velocity interferometer system (VISAR). High-resolution measurements on the plastic shock wave front are carried out, and detailed experimental data that are needed for evaluating the estimating simulation of the shock wave profile are obtained.

    ABE Akihisa, KOHARA Kozo
    The present study reports the numerical prediction method of particle velocity variation with shock wave propagation in metals. The key of the present method is evaluation of the shock viscous stress in the shock wave front. The shock viscous stress is calculated from equilibrium stress obtained by the estimate method of temperature inside shock wave front developed by Sano & Abe. The shock viscosity is incorporated into a one-dimensional finite difference wave code. The present calculation is executed for 6061-T6 aluminum and iron, and these results are compared with experimental data. The present results show that it can reproduce more accurately the particle velocity variations on the shock wave fronts in 6061-T6 aluminum and iron.

  • Deformation Problems of Gas Interfaces of Defferent Densities Generated by Shock Waves (Light/Heavy Interface)
    ABE Akihisa
    This paper reports numerical and analytical studies of the interaction problem between a gas interface of different densities and shock waves. The interface is formed between air and SF6 (light/heavy interface, i. e., the incident shock wave propagates from air to SF6), and there is a sinusoidal perturbation on the initial interface. The interface deformation process and the growth rate of a sinusoidal perturbation on the interface are investigated after shock wave interaction. Numerical simulation is carried out using the second-order TVD finite difference scheme, and the Euler equations are solved. Theoretical impulsive growth rate obtained using the stable velocities on the interface after shock interaction is compared with results of the numerical simulation. In the case of incident shock Mach numbers Ms < 2 and amplitudes of perturbed interface η_0k < 1, good agreement is obtained.

  • Flow Structure behind a Shock Wave Discharged from a Square Cross Section Shock Tube
    ABE Akihisa, WATANABE Masato, TAKAYAMA Kazuyoshi
    The structure and behavior of a vortex ring and secondary shock waves which were generated behind the shock wave discharged from the open end of a square cross section shock tube were investigated experimentally and numerically. Double exposure diffuse holographic interferometry was used to observe this complicated three dimensional shock wave phenomenon. This diffuse holographic interferometric visualization is particularly useful to understand three dimensional flow. The TVD finite difference numerical simulation was carried out by solving the three dimensional unsteady Euler equations. A comparison was made between experimental results and computational results. These results clarified the generation and the transformation of the vortex ring and the behavior of three dimensional secondary shock waves.

    舶用バラスト水処理や船底付着生物除去を始めとする様々な海上移動体や海洋構造物への生物付着を防ぐ経済的効率的技術の確立が国際的に求められている。本研究では、衝撃圧力によって誘起する微小気泡運動の有効活用により、酸化作用物質（フリーラジカル）の効率的生成方法および条件を見出し、省エネルギーかつ安全安心な海洋微生物処理技術を確立し、海事産業分野に貢献できる海事科学分野発の圧縮性流体力学に基づく新しい基盤技術を創出することが目的である。 本年度の研究では、単一気泡の衝撃波による一連の崩壊運動によって生じるOHラジカルの生成量の理論的予測について検討を行なった。数十マイクロメートルオーダーの直径の気泡が最大圧力約6 MPaの水中衝撃波の圧力作用を受けると、気泡は収縮膨張運動を行なって崩壊する。気泡の収縮時には、気泡内の圧力及び温度の著しい上昇を伴い、その熱エネルギーによって気泡内の水蒸気が解離し、OHラジカルが生成されると考えられる。水蒸気からOHラジカルが生成するためには、約5000 Kが必要であることが知られている。本解析では、衝撃波作用による空気泡の収縮現象が高速で、ナノ秒オーダーの短時間であることから気泡内の空気及び水蒸気は断熱圧縮される仮定の下、水に関する27種類の化学種が関与する化学反応式を用いて解析を行なった。その結果、気泡内温度が最大となるタイミングとOHラジカルの生成量が最大となるタイミングは異なることが見出された。

    球面波頭内の小さい幅の線形ひずみ波に対して,ランキン-ユゴニオ型跳躍式を導き,半径方向粒子速度の跳躍に及ぼす波頭の伝播に伴う幾何学的減衰効果を評価した.幅の10倍以上の伝播距離に対して,球面波頭に対する跳躍が平面波頭に対する跳躍に近づき,幾何学的減衰効果が無視できることが示された.さらに,線形ひずみ波に対して一般跳躍式を導いた.半径方向粒子速度と半径方向応力の跳躍に及ぼす体積ひずみ速度,体積ひずみ加速度,減衰の影響を評価しつつある. 口径40mmの一段式軽ガス銃を用いて平面衝突実験を行った.飛翔体はABS樹脂製であり,樹脂の先端面に6061-T6アルミニュム円盤を取り付けた.飛翔体速度はマグネットフライヤー方式とレーザーカット方式の両方で測定した.4本のピンセンサーにより,衝突平面度を測定した.本実験の主計測である,6061-T6アルミニュム標的板裏面の自由表面速度(粒子速度の2倍)の計測には,主に速度干渉計(VISAR),アルゴンイオンレーザー,プルーブ,オッシロスコープからなる高時間分解能レーザー速度干渉計システムを用いた.計測した粒子速度-時間プロフィルと比較するために,衝撃粘性応力を理論的に見積もり,衝撃粘性応力を組み入れた1次元波動計算コードを開発した.252,311,390m/sの飛翔体速度で計測した粒子速度-時間プロフィルを計算プロフィルと比較した.252と311において比較は良好であったが,390m/sにおいて両プロフィルは少しずれた.

  • Alloying Process and development of joining and alloying techniques for metals

    A method of producing metal alloy on a very short time scale has been developed. One metal powder is sandwiched between bars of a second metal usually of a lower melting point and a lower electrical resistance, and an electrical current passed through under pressure. Joule heating is mostly generated in the powder because of its high resistance, causing it to melt first. The region of bar making immediate contact with the molten powder then melts, and intermixing on a local scale takes place. The boundary surface between this mixed portion and the bar propagates approximately as a front of a one-dimensional plane wave outward until melting is finished. The wave fronts travel further into the bars the longer the current is applied. Various metal alloys were produced using the combination of different kinds of metals and metal powders. To confirm the validity of the alloying process inferred above, thermodynamics of irreversible processes was developed, and heat waves were analyzed. This analysis of heat waves, which was submitted to Japanese Journal of Mechanical Engineering, revealed the validity of the inferred alloying process. This analysis is further developed by incorporating the intermixing process in the analysis and by measuring temperature-time profiles in the molten powder and mixed portion.

    本研究では、収縮衝撃波による超高圧力の発生とその利用技術の発展に関して重要となる収縮衝撃波と異種気体界面との干渉問題について数値シミュレーションによる解明を試みた。計算は衝撃波を伴う圧縮性流れのシミュレーションに良く使用され不連続面の捕獲性能に優れた二次精度風上型TVD差分法(Harten-Yee type)を用い、Euler方程式を解いた。スキームの確認として平面衝撃波と正弦曲線形状の界面との干渉問題を解き、Meshkovの実験結果と比較した結果、定性的に良好な結果を得た。問題解明の第一歩として界面形状の変化や干渉後の衝撃波の伝播挙動等を明らかにするため単純な正方形状の界面を選択し、初期衝撃波マッハ数1.5の円筒収縮衝撃波を界面に入射させた。fast/slow現象ならびにslow/fast現象を模擬するため、異種気体界面にはAir/SF6界面とAir/He界面を用いた。その結果界面形状の変化は、透過衝撃波背後の流れよりも、衝撃波が界面に入射した直後に発生する界面での反射波(圧縮波または膨脹波)が界面の上流側の粒子速度に著しい影響を与えてその粒子速度によって生じることが明かとなった。さらに周方向への透過衝撃波の反射がfast/slow現象ならびにslow/fast現象の特徴的な海面形状を決定する重要な要因となることがわかった。したがって、初期異種気体界面形状の波数が増加すれば短時間のうちに周方向から圧縮波または膨脹波が伝播してくることになり不安定性の成長に著しく影響することになると考えられる。また、本計算では円筒座標系とカルテシアン座標系を用いて計算を行い、界面形状の格子の種類による影響を調べた。本計算に使用した計算機(神戸商船大学計算センター)の能力不足のため充分な格子を配することが出来なかったが、界面形状は1格子の乱れでも最終的に著しい振幅の増大がみられ、初期界面形状に対する格子形状の選択が重要であることがわかった。
