2D Simulation of Effects of Position of Baffles on the Removal Rate of Solids in a Sedimentation Tank

Abstract:

In this paper, we use solid–liquid two-phase mixture model and the k-ε turbulence model to numerically simulate the effects of the position of baffles on the removal rate of solids in a sedimentation tank. The PISO algorithm is used to decouple velocity and pressure. The distribution of sludge concentration on different cross-sections is obtained by the proposed model.
