    Abstract
  • A new kind correction to Baldwin-Lomax turbulence model (BL-entropy) based on the concept of entropy was proposed. The supersonic plane, two-dimensional supersonic compression corner and expansion-compression corner which were representative in the engineering area were chosen in the numerical simulation to evaluate the performance of this model. It is found that BL-entropy can conquer the essential deficiency of the original model by providing a more physically correct length scale in the supersonic complex flow. Moreover, this method is simple, computationally fast and general, making it applicable to other models related with the supersonic boundary layer.
