The Reynolds stress model (RSM) and Fluent program were used to simulate the three-dimension flow field in PV type cyclone,and the SIMPLE algorithm was used to solve the governing equation in three-dimension BFC( Body-fitted coordinates) grids.

• 采用雷诺应力模型(Reynolds stress model,简称RSM),在三维贴你坐标系下采用SIMPLE算法求解控制方程,应用Fluent程序数值模拟PV型旋风分离器内三维流场。
