Transition prediction e^N method and its software development for supersonic boundary layers

Research status of boundary layer transition prediction is reviewed at first; the advantages and disadvantages of the present three kinds of boundary layer transition prediction methods are summarized; from the aspects of theoretical and engineering application, the shortcomings of existing transition prediction e^N method and its transition prediction software are emphatically analyzed, and the development trend of the future transition prediction method and its software is forecasted; then from the point of view of engineering application, an implementation approach of engineering oriented transition prediction software based on transition prediction e^N method for supersonic boundary layer is put forward. By continuously improving and perfecting the traditional transition prediction e^N method, combining with the experience of flow stability analysis and transition engineering application, setting up a series of knowledge databases of eigenvalue, receptivity coefficient and transition criterion, it is expected to develop a practical, fully automatic, highly efficient, friendly user interface and engineering oriented software of transition prediction for supersonic boundary layers.
