Abstract: In this paper, a numerical two-fluid flow model combining with the Realizable k-Ε

turbulent model for compressible viscous fluid is presented for the computation of flow

characteristics in an aeration tank; and the equations are solved with the finite volume method.

A multigrid technique based on the full approximation storage (FAS) scheme is employed to

accelerate the numerical convergence. The numerical results for velocity and turbulent kinetic

energy distribution in the aeration tank are obtained. It is shown that the Computational Fluid
