Experimental Study of Flowfields Over a NACA0012 Airfoil with Ground Effects
지면효과를 받는 NACA0012 익형주위 유동장의 실험적 연구
Abstract
Experimental and numerical studies are conducted to investigate the flow field over a NACA0012 airfoil with ground effects. In experiment, the ground is simulated by a moving belt system. From the comparison between the experimental and numerical results, it is concluded that the velocity gradient over the ground plane causes the increments in pressure coefficient on lower surface of the airfoil and reduces the suction peak at the leading edge.
