Vortex Developments Over Naca 0015 Airfoil with Trailing Edge Jet
The flow over a NACA 0015 airfoil with a trailing edge jet (jet flap) is investigated using computational and experimental capabilities to determine the influence of the jet on vortex developments over the airfoil. The computational modeling of steady flow at a Reynolds number of 43,000 at fifteen and twenty degrees indicates that as the jet mass flow rate is increased, the trailing edge jet suppresses vortex development, and in some cases, reattaches the flow. Experimental visualization shows the suppression of vortex structures in both steady and accelerating flow. The trailing edge jet may thus be a possibility for vortex control.
