Turbulent Flow Over a Backward-Facing Step Using Penalty and Equal-Order Finite Element Methods
Two-dimensional steady incompressible turbulent flow over a backward-facing step was calculated using equal-order and penalty function finite element methods. The standard k–ε turbulence model with wall functions was applied. Results from both of the methods for pressure-velocity coupling look similar to each other. The greatest discrepancy was observed for the velocity vector plots behind the step. While the equal order method showed physically correct behavior of velocity near the walls, the penalty function method gave oscillations for the velocity component parallel to the wall.
