弹性碰撞

We overcome the previous drawbacks because one of the most important improvements is that we introduce a dissipative viscous force to simulate the effect of collision between gas clouds.

我们的结果同观测符合得很好，克服了以往研究中的缺憾(如环不稳定，位置不准确等)，主要的原因是由于我们引进了一个粘滞耗散过程来描述气体粒子之间的非弹性碰撞。

The results show that the stronger the particle-particle collisional dissipation and gas-solid drag force, the more heterogeneous the flow structure.
