A stochastic method for calculating the collision and agglomeration in an electrostatic agglomerator

The present study developed a stochastic model to simulate collision and agglomeration between bipolarly charged particles based on the classical Euler/Lagrange approach. The particle initial charge was sampled from the charge distribution by statistical analysis. Collision was determined by comparison of collision probability and a random number. The effect of particle charge on collision and agglomeration was embodied in the agglomeration criteria. Whether a coagulation event occurs or not was determined by comparison of particle´s adhesive and repulsive energy. The effect of collision and agglomeration on the particle charge distribution and diameter distribution were investigated.
