The effect of ground proximity on the inviscid flow around three-dimensional bluff bodies
Abstract
The source panel method is used to simulate the inviscid flow field of three-dimensional bluff bodies in ground proximity. The forebody pressure drag is found to decrease as the ground clearance is reduced. The frontal stagnation point moves toward the ground plane with reducing the ground clearance. The ground effect on the top flow is negligible but the bottom flow is strongly influenced by the presence of the ground plane.
