Schematic of Backward-Facing Step.
All calculations presented here use a two-dimensional grid.
File All of the archive files of this validation case are available in the Unix compressed tar file bstep.tar.Z . The grid was also clustered in the streamwise direction near the recirculation region to improve resolution. The coordinates in both files are in units of feet and the step height H is 0.5 inches. The Chien k-epsilon model was initialized from the existing solution and turbulent viscosity of the SST model after 35000 iterations. At that time, the Chien k-epsilon model is initialized from the existing turbulent viscosity.
