Abstract：In this work, we would like to bring in the compressibility modification to the γ -Reθ transition model and meanwhile maintain the model's locality. The limited published experiment correlations and a part of physical mechanism of supersonic transition will be considered in our modification and modeling process. Some fundamental numerical experiments will be performed to test the modification. Then the modified transition model will be applied in the previous transonic turbine vane again and other high-temperature parts in gas turbines containing the CHT effects and transition flow features. Better results, which can indicate the improvement of the model to simulate supersonic transition flow in CHT problems, are expected.
