AbstractA simple model was proposed to predict the transition region of compressible flow. An algebraic type of RNG (Renormalization Group) model was employed with modified expressions for dissipation rate and length-scale. A 2D flat plate flow with no pressure gradient was calculated to validate the model. The results showed favorable agreement with theoretical values, which suggests its capability to predict the transition cases for simple flow.
