摘要：

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. (C) 2001 Elsevier Science Ltd. All rights reserved.
