Backward Facing Step By Jordana Ram Simscale Large eddy simulation (les) was used to study the turbulent ow over a backward facing step. the simulations examine the details of the turbulent ow’s separated and reattaching regions created by the step geometry. A direct numerical simulation of turbulent flow over a backward facing step is performed. to control flow separation, a wall normal body force in the form of a wave machine like traveling wave is applied to the top surface of the step. The water surface response to subcritical turbulent flow over a backward facing step (bfs) is studied via high resolution large eddy simulation (les). the les method is validated first using data of previously reported experiments. This tutorial will cover the basics of setting up and running the common fluid problem of the flow over a backward step. additionally, a comparison of stream results will be presented. the backward step problem is commonly used to validate simulation codes’ turbulence models.

In the present work, large eddy simulation coupled with immersed boundary (les ib) method is applied to simulate a backward facing step (bfs) flow, which is a canonical fluid dynamics problem involving flow separation, recirculation and reattachment that are common in many practical applications. The backward facing step is an interesting case for studying the performance and solution strategy of a turbulence model. in this case, the flow is subjected to a sudden increase of cross sectional area, resulting in a separation of flow starting at the point of expansion. The paper presents the direct numerical simulation (dns) of a confined backward facing (bfs) step geometry with a flow of two fluids with prandtl numbers 0.005 and 0.1. The les code in openfoam is used to simulate the flow over a backward facing step using three different mesh sizes. the maximum pressure values of the three different cases are compared and a mesh convergence study is carried out.
