摘要:
利用实验测得的与流场有关的特征参数值和相关理论 ,确定粉尘的本构方程。基于该方程 ,利用激波极曲线理论 ,可得到该流场特征参数随激波速度变化的关系曲线。对该流场进行数值模拟 ,可描述波后的流场结构。理论计算和实验结果较为一致
Abstract:
The constants in the const itutive equation of granular material have been determined according to the experimental results and analyt ical formulas based on shock polars. The numerical invest igations on interact ions of shock waves with air/ granular interface were carried out by using the const-i tut ive equat ion. The calculated flow fields induced by the interact ions are in good agreement w ith that show n by experimental photographs recorded by the shadow graphs and the pulsed X- ray shadow graphs with t race particles. Effects of the strength of shock waves and the material density of particles on f low fields were discussed.
