Abstract

Optimization 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.

跨声速翼型切向喷流的颤振控制优化

对超临界跨声速翼型上表面切向喷流进行了颤振条件下的优化设计。求解二维非定常reynolds -average Navier-Stokes方程来模拟翼型的流动。采用Spalart-Allmaras湍流模型对方程进行了封闭。狭缝喷嘴的位置和喷射强度是不同的。确定了以最小喷流强度抑制冲击的最佳吹气位置。
