Abstract

A numerical method is developed for steady and unsteady turbulent flows with significant regions of separation. A finite element formulation of the NavierStokes equations with a modified BaldwinLomax eddy viscosity closure is used. The method of averaging is employed to obtain a periodic solution of unsteady flow. The formulation is tested on a problem of flow over a backwardfacing step and the results are compared with experimental and other numerical results. The gross features of both steady and unsteady flows are reasonably well predicted by the numerical analysis, at least for the limited range of parameters tested so far.
