Abstract

The predictions of flow phenomenon that occur in high lift systems have proven to be challenging using the Reynolds-Averaged Navier-Stokes (RANS) equations with turbulence models. The complex interactions that occur among different elements of the wing can be difficult for turbulence models to accurately predict. Results from the recently developed Wray-Agarwal (WA) one-equation turbulence model, the frequently used Spalart-Allmaras (SA) and shear stress transport (SST) k-ω turbulence models are compared to experimental results to evaluate each model’s relative accuracy. It is shown that at lower angles of attack the computed lift from each turbulence model has similar accuracy as in the experimentally determined lift. At higher angles of attack the WA model shows decreased accuracy while the SA and SST k-ω have similar accuracy. For other computed flow field quantities, the experimental data generally matches closest to the results from the SA model on a fine grid. In some cases, the WA and SST k-ω model have improved accuracy over the SA model on the same grid.
