摘要：
The current work presents progress in the effort to numerically simulate the flow over high-lift aerodynamic components, namely multielement airfoils in either a takeoff or landing configuration. The computational approach utilizes an incompressible flow solver and an overlaid chimera grid approach. A detailed grid resolution study is presented for flow over a three-element airfoil. Two turbulence models-a one-equation Baldwin-Barth model and a two-equation k-omega model-are compared. Excellent agreement with experiment is obtained for the lift coefficient at all angles of attack, including the prediction of maximum lift when using the two-equation model. Results for two other flap riggings are shown.
