The application discloses a transition prediction method considering wall heating and cooling effects, and simplifies and modifies a stability basic transport transition model, so that the application range of the stability basic transport transition model is extended to the influence of the non-adiabatic wall effect considering the generalized wall heating and cooling, the localized momentum thickness Reynolds number expression and the transition starting momentum thickness Reynolds number expression considering the wall heating and cooling effects are constructed, and the two expressions are coupled into gamma the transport model, the transition transport model considering the wall heating and cooling effects is obtained after wind tunnel example verification, and then the transition prediction of the stratosphere high-altitude airship under the wall heating and cooling effects is realized. The experiment proves that the application can accurately reproduce the significant upstream movement of the transition front caused by the wall heating, and therefore the application provides a robust engineering basis for the aerodynamic design and optimization of the future laminar platform considering the non-adiabatic wall effect.
