Verification

Since so many study cases have been done for this problem, it is easiest to validate our simulation against those cases. In this tutorial, “Backward-Facing Step Flows for Various Expansion Ratios at Low and Moderate Reynolds Numbers” by G. Biswas, M. Breuer, and F. Durst will be our study case and the streamlines will be compared to the simulation. In order to plot a streamline in AIM, select streamline from the Add drop down menu. Select the inlet as the seed location, change the Distrbution to Based on mesh, retain 1 as N and change the Direction to Forward and backwards.
