摘要

A full three-dimensional en transition prediction method and a laminar boundary layer code are coupled to the three-dimensional Reynolds-averaged Navier-Stokes (RANS) solver for predicting the transition point automatically during the simulation of the flow around the infinite swept wings. The RANS solver provides the wall pressure coefficient cp for solving the laminar boundary layer equations. The three-dimensional compressible linear stability code was used to analyze the laminar boundary layer's velocity and temperature profiles, and the full en method was used to find out the transition point. If the transition point cannot be found by using the full en method, then the laminar separation point is set as the transition point approximately. Finally, we returned the transition information to the solution procedure of the RANS solver. Repeating the above process, we can detect the flow transition point automatically during the ongoing RANS computation. The calculation results are in good agreement with the experimental data, showing the reliability of our method in predicting the transition point in the boundary layer flow around infinite swept wings.
