The laminar-turbulent transition is an old but still not a fully solved problem, which is mainly studied from the following aspects: (1) how the perturbation is generated and the receptivity problems (2) linear and nonlinear problems during the evolution of the perturbation (3) numerical simulation of the transition problem and the actual prediction. Considering that the power system of the vehicle is working in a low Reynolds number environment for a long time when flying at high altitudes. In this article, the research focuses on the turbulence model with the introduction of the AGS transition model is used to simulate the two-dimensional flat plate boundary layer transition in the low Reynolds number case, and to predict the transition location by combining the stability of different positions of the flow process, and to evaluate the accuracy of the transition model in comparison with other numerical simulation methods.
