To investigate particle motion in detail, we performed a numerical simulation of the crystal particle motion in a stirred vessel using an Euler-Lagrange approach with Distinct Element Method (DEM) coupled with Large Eddy Simulation (LES) of flow fields. Particle motion affects the particle impact on impeller blades and vessel walls, as well as the particle concentration distribution. The particle impact energy and impact frequency were estimated based on the instantaneous relative velocity between a particle and an impeller. Results clarified the effects of impeller rotational speeds on the particle impact, showing that the particle impact energy imparted on the loading faces of impeller blades and baffles are greater than that on the vessel walls.
