Computation of two-dimensional blocked flow normal to a flat plate

A commercial CFD code (FIDAP) is used to compute two-dimensional blocked flow normal to a flat plate. Both quasi-steady and transient computations were performed using a variety of turbulence models. The quasi-steady computations underpredict drag and are not sensitive to the choice of turbulence model, but provide excellent prediction of the effects of blockage on drag. The transient simulations do a very good job of predicting the actual value of the drag, and are sensitive to the choice of turbulence model. The application of CFD to separated flow aerodynamics is discussed.
