Abstract

In the present study, the MIXING fluids flow in the twin and circular mixers is investigated by using an improved robust weakly compressible SMOOTHED PARTICLE HYDRODYNAMICS method. In order to remove the SMOOTHED PARTICLE HYDRODYNAMICS complications and according to a predictive corrective scheme, a robust modified algorithm which uses the advanced second order discretization, pressure velocity decoupling, kernel gradient corrections and shifting algorithm is offered. After the verification and validation of the present algorithm for the moving boundary problems, the present algorithm is applied for investigation of the MIXING behaviors of the twoblade circular and TWIN CHAMBER mixers. By investigation of the MIXING paths, the proper geometry for the two-blade mixers is proposed and examined. The effects of the rotation direction of the blades, geometry and Reynolds number on the MIXING rate are investigated. The results show that the TWIN CHAMBER mixer can improve the MIXING performance over 60% in comparison with the CIRCULAR CHAMBER mixer while the case with CIRCULAR CHAMBER and same direction rotation of the blades has the weakest performance among the cases which have been examined.
