Title

Numerical Studies Of Turbulent Separation In Forward Facing Step Flows Using K - Ε, Sst, S-A And Les

Abstract

Computational studies of transient quasi-three-dimensional supersonic flows over a forward facing step are carried using the k - ε, SST and SA turbulence models. Numerical computations are carried out for five different Reynolds numbers, Re= 3.84x104-106. The numerical studies concern the influence of Reynolds number and step aspect ratio on the flow dynamics. The results show that the both parameters influence the flow field in a particular manner. With the increase of Reynolds number the flow separation occurs closer to the backstep. Flow reattachment is observed downstream the channel. © 2013 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.
