Flow over a 2D Backward Facing Step
In this project, you will simulate a laminar flow over a backward facing step- one of the benchmark CFD problems. You will be solving the complete Navier-Stokes equation for a 2D laminar viscous flow in OpenFOAM. This project will help you learn how OpenFOAM works and how you can make an effective use of it to solve real-time CFD problems.

Flow over a 2D Backward Facing Step
In CFD, the benchmark problems are used to validate CFD models. Flow over a backward facing step is one such problem. Because of its simplicity, it can be simulated experimentally for a variety of conditions and this data is used to establish confidence over a CFD model. This problem is used to validate physics involved in boundary layer separation, like boundary layer thickness, re-attachment length and wall-skin friction coefficient. In this project, you will set up this problem and solve the in-compressible laminar viscous flow Navier-Stokes equations in OpenFOAM using the transient icoFoam solver. You will then extract the velocity data using a line probe near the back step where the flow separation occurs and plot in Paraview. You will also validate the results for different values of grading factor.
