AbstractThe γ-Reθ Transition Model was applied to predict the supersonic boundary-layer transition on cones and the results were compared with flight experiments and wind tunnel ones. The model failed to predict important effects in high Mach number flows, i.e. higher mode instability, heat transfer and entropy layer. Although the prediction accuracy of the current γ-ReθTransition Model in high Mach number flows is not good, the distinctive advantages of the model such as low computation load and suitability for parallel computing are desirable and should be maintained in improvement to come. Fundamental data to make the correlation which involves the effects of Mach number, heat-transfer, entropy layer and cross-flow etc. are needed.
