摘要：
A new transition/turbulence model considering the modes of instability and the compressibility effects is established. Based on the Menter's SST model, it adds the contribution of nonturbulent fluctuations into the effective viscosity. The present model is validated by comparing the results of subsonic flat plate, supersonic straight cone and hypersonic flared cones at zero angle of attack with available experiments. In general, good agreement is indicated.
