NUMERICAL OPTIMIZATION OF FLOW CONTROL BY TANGENTIAL JET BLOWING ON TRANSONIC AIRFOIL
K.A. Abramovaš, V.G. Soudakovš; šTsAGI, Russia
Numerical RANS and URANS simulations are carried out to optimize buffet control on transonic airfoil by tangential jet blowing. A jet of compressed air is blown from small slot nozzle tangentially to airfoil upper surface in the region of shock location to reduce shock-induced separation and to delay buffet onset. Numerical optimization is performed to determine parameters of flow control.
