Application of CFD simulation to suspension crystallization-actors affecting size-dependent classification

A size-dependent classification function, which is a parameter used to char acterise crystallization in imperfectly mixed suspensions, was simulated us ing CFD. The CFX4.2 program was employed to simulate the local particle-siz e distribution in a multifluid flow using the k - epsilon turbulence model with respect to interface transfer between the particles and the solution. The problem was studied three dimensionally. A sliding grid technique was u sed to simulate the transient flow in the mixing tank. The size-dependent c lassification was calculated based on the local particle-size distribution. The factors that affect the classification function are discussed. (C) 200 1 Elsevier Science B.V.
