Abstract To simulate particle rotation characteristics, a gas-solid impinging stream mathematical model was established by DSMC method with the consideration of particles rotation. The experimental data were used to verify the proposed model. The effects of initial velocity, flow rate and diameter on particles rotation characteristics were analyzed. The results show that particle rotation mainly generates in impinging area. The average rotation rate is increased with the increasing of initial velocity, feed rate and diameter of particles.
