摘要：
AbstractOptimization of tangential jet blowing on the upper surface of a supercritical transonic airfoil under buffet conditions was carried out. Two-dimensional unsteady Reynolds-averaged Navier-Stokes equations were solved to simulate the flow past the airfoil. The Spalart-Allmaras turbulence model was used to close the equations. The location of the slot nozzle and the intensity of the jet blowing from it were varied. The optimal location for blowing with minimum jet intensity to suppress buffet was determined.
