摘要
采用有限元软件包ANSYS/LS-DYNA,针对圆盘击水的过程进行数值模拟分析。在研究中分别采用基于光滑粒子流体力学的方法和基于有限体积法的ALE法的两套方案计算,并分别对比计算了圆盘成功击水的相应的临界角度以及自转的影响。并将两套方案与试验结果作对比,从而得出一些具有工程参考价值的图表曲线。
Based on the finite element package ANSYS/LS-DYNA, numerical simulation analysis for the disc splashing into the water process are researched. The two options, ALE algorithm based on the finite volume method and SPH algorithm based on smoothed particle hydrodynamics method were used to calculate in the study, and cal- culation of the critical angle of the disc successfully splashing into the water and the effect of rotation, the two op- tions compared with the experimental results, so as to arrive with the project reference value of graphic curves.
