Enhancement of lift to drag ratio for a wing using thermal forcing

The aim is to enhance the lift to drag ratio produced by a wing with a cambered profile by thermal forcing its partial lower surface. Reynolds number is considered in the laminar regime. The efficacy of control technique has been checked at various Mach number and angle of attack. The overheat factor, which is the ratio of the temperature of the heated portion to free stream temperature has also been varied to study its role in the control technique. The governing equations of continuity, momentum, and energy have been solved using commercial package Fluent^®. As of now, the proposed mechanism for the enhancement of lift to drag ratio is the increase in vorticity generation near the trailing edge because of the variation in viscosity. This brings about a net increase of circulation about the wing which results in higher lift. The other possible mechanism for the phenomenon is further being explored such that advancement in Micro-Air Vehicles technology can be done
