大尺度网格下 DSMC 仿真碰撞概率的修正方法
A modification technique of collision probability on coarse grid in the direct simulation monte carlo method
摘要
Abstract
A new modification technique of collision probability with least square method and sub-relaxa-tion technique is introduced to improve simulation precision in DSMC with coarse grid size.The new method is applied to direct simulation Monte Carlo method based on unstructured tetrahedral cells.Flow around blunt cone is investigated,and the numerical results confirm feasibility of the modification tech-nique.关键词
