| 摘 要： | The purpose of this work is to improve the k-ω-γ transition model for separationinduced transition prediction. The fundamental cause of the excessively small separation bubble predicted by k-ω-γ model is scrutinized from the perspective of model construction. On the basis,three rectifications are conducted to improve the k-ω-γ model for separation-induced transition.Firstly, a damping function is established via comparing the molecular diffusion timescale with the rapid pressure-strain timescale...
