Flow over a downstream‐facing step is predicted using the F.E.M. A two‐equation model of turbulence is employed where the transport of turbulence kinetic energy and dissipation rate are depicted using transport‐type equations, i.e. the two‐equation model of turbulence. The results obtained are compared with other models and experimental results. Generally, the model was found to be under‐predictive with regard to the reattachment length when previous empirical data was used in the transport equations.
