Numerical Simulation of Hydraulic Characteristic of Oxidation Ditch

Article Preview

Abstract:

A numerical simulation study of the hydrodynamics of oxidation ditch is presented. 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 as a turbulence model the RNG κ-ε model with wall functions is used. The numerical results for velocity, as well as for the pressure distribution in the oxidation ditch are obtained.
