Abstract
The ifxed transition location calculation method and free transition prediction method ofγ-Reθtmodel based on SSTk-ωturbulence model, were implemented to investigate the lfow transition around RAE2822 airfoil. The transition location was obtained byγ-Reθtmodel, and then ifxed to verify the method of ifxed transition location. The results were compared with the corresponding results of full turbulent prediction and other codes. It can be concluded that both methods can effectively capture the lfow transition phenomenon of the target airfoil, the results of ifxed transition location calculation almost reproduce that of free transition prediction method.关键词
