What will you do in this project?

In this project, you will simulate an laminar viscous flow over a backward facing step using the the in-compressible transient-state solver called icoFoam. You will work on the Linux command line interface to run OpenFOAM simulations. You will specify the geometry, mesh information, and initial and boundary conditions inside the respective C++ files. You will then create the mesh and run the simulations by typing commands in the terminal window. The simulation results will be viewed and post-processed using Paraview. You will run the simulations for multiple values of Grading Factor and validate the results.

  • Define the mesh, initial and boundary conditions inside OpenFOAM C++ files
  • Create mesh and run the simulation in the Linux terminal window
  • Post-Process simulation results using Paraview

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. 

  • Use icoFoam solver to simulate flow over a backward facing step
  • Use Paraview to generate useful plots
  • Validate the results for different grading factors
