摘要：

This work is focused on studying the aerodynamic benefits of surface heating of airfoil in low Reynolds number flow. Numerical simulations of NACA 0012 airfoil in a flow of Reynolds number 2.5x 10(5) were performed employing Transition SST turbulence model. The airfoil was heated at multiple zones and the heat supplied came via two sources: a constant heat source and a time-varying heat source. It was observed that heating the lower nose of the airfoil with a constant heat source shows drag reduction at all angles of attack and periodically heating the same zone gives more significant reduction for 0 degrees to 6 degrees AOA.
