Abstract

A detailed analysis of flow over a backward facing step is presented for two types of outlet boundary conditions, namely traction free and zero vertical velocity and zero horizontal traction, and for Re numbers up to 229. The computational scheme that is used is a mixed finite element method based on 'assumed-deviatoric-stress, -pressure, -velocity'. The final finite element equations involve the nodal velocities and the constant term in the pressure field in each element as unknowns. The convective acceleration term is treated via a standard Galerkin scheme.
