02.3 - Basic Fluid Dynamics and Flow ControlINVESTIGATION OF FLOW CONTROL OVER THE SUPERCRITICAL AIRFOIL BY TANGENTIAL JET BLOWING AT TRANSONIC SPEEDSA.V. Petrovš, A.V. Potapchikš, V.G. Soudakovš; šTsAGI, Russia Numerical RANS simulations are carried out to characterize buffet phenomenon on transonic airfoil. A jet of compressed air is blown from narrow slot nozzle tangentially to airfoil upper surface in the region of shock location to reduce shock-induced separation and to delay buffet onset. Experimental investigations are also performed and compared with numerical simulations. |
