Experimental study of the movement of particles in the coupled field of low temperature plasma and cyclone

An investigation was made of the movement of particles in the coupled field of a low temperature plasma and cyclone with PIV in order to study the moving trace of particles' movement in an electrostatic cyclonic collector. The experimental results show that the plasma field had little effect on the tangential velocity of particles, but had an obvious influence on the radial velocity. The tangential velocity of airflow had a great impact on particles' tangential movement. With the particles going down the cyclone tube, their tangential velocity dropped. Their radial velocity dropped as the radius enlarged from the center to the collecting wall of the tube. The plasma field could improve the radial velocity of particles by 5%-10%, but the motion along the radius was determined by the cyclone.
