Flow Control Predictions Using Unsteady Reynolds-Averaged Navier-Stokes Modeling: A Parametric Study

摘要

An extensive computational study was conducted with RANS and URANS and three different turbulence models in application to the hump model case from a flow-control validation workshop held in 2004. Many of these cases were not part of the workshop itself, but were included in the experiment. They included investigations into the effects of Reynolds number, control magnitude, and control frequency, and have not been computed before. The purpose of this study was to investigate the effectiveness of RANS and URANS CFD for predicting trends in this type of flow-control application, where it is already known to mispredict absolute levels.
