shadow-Moire test

A Shadow Moire System Based on Two Ronchi Gratings Structure for the Measurement of 3D Profile;

基于双光栅结构的阴影莫尔法三维形貌测量

And a good qualitative agreement between the distributions of the predicted density gradient and the experimental shadowgraph was obtained.

根据数值结果,详细讨论了初始流场、火药燃气流场的形成与发展以及与弹丸的耦合和相互作用过程,并与膛口流场的实验阴影照片进行了对照,两者在定性上是吻合的。
