摘要
采用可压缩多介质流体高精度PPM方法对实验模型进行数值计算,针对果冻内外界面10模峰对峰、峰对谷振幅为1mm扰动模型,给出了与实验相对应时刻的数值计算结果,并对果冻内外界面位置、速度和加速度历史进行了详细分析。计算结果再现了复杂的实验现象,基本物理现象与实验图像以及计算结果和实验数据均相吻合。
In this paper,we applied the high-resolution compressible multi-fluid PPM method to simulation of the instability of the jelly surfaces under the imploding drives.The outer and the inner surfaces of the jelly are set initially by model 10,1 mm in top-top and top-bottom disturbance amplitude.Shape,position,velocity and acceleration of the outer and the inner surfaces of the jelly computational results are given.The numerical images are in excellent agreement with the basic physical phenomena.
