Simulation of 3D Gas-Liquid Two-Phase Flow Characteristics of Carrousel Oxidation Ditch

Abstract:

In this paper, the gas–liquid two-phase mixture model with the k-ε turbulence model was used to numerically simulate the characteristics of an oxidation ditch. The proposed model concerns with the drag force and the drift velocity. The numerical method is based on a pressure-correction algorithm of the SIMPLE-type. A multigrid technique based on the full approximation storage (FAS) scheme is employed to accelerate the numerical convergence, while the κ-ε model with wall functions is used. The numerical results for velocity and turbulent kinetic energy in the oxidation ditch are obtained．
