Numerical Simulation in High Lift Aerodynamics

Kurzfassung

The application of CFD methods for the solution of the Euler and Reynolds-averaged Navier-Stokes equations is highlighted. Major areas of application of RANS methods are the prediction of maximum lift as well as the treatment of complex 3D configurations. The prediction capability with respect to the first item is demonstrated with the computation of maximum lift for a 3-element airfoil, including an assessment of the influence of numerical parameters. The RANS computation of a wing/fuselage configuration with deployed high lift system serves as an example for the treatment of complex 3D flows. On a similar configuration the investigation of wake vortex characteristics based on an Euler solution is discussed. Finally a setting optimization of a 3 element airfoil is presented in order to give an outlook to future trends in CFD development and applications in high lift aerodynamics.
