| Research Abstract |
Attrition of crystal particles is one of the most significant phenomena to operate a crystallizer stably. On this subject we performed the Lagrangian simulation of crystal particles motion and particles collision on obstacles in a stirred vessel. 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 was greater than that on the vessel walls.
