Ground vortex formation for uniform and nonuniform jets impinging on a ground planeAn experimental investigation of the impingement of a single circular jet on a ground plane in a cross flow is presented. This geometry is a simplified model of the interaction of propulsive jet exhaust from a V/STOL aircraft with the ground in forward flight. Variation of observed ground vortex size with cross flow-to-jet velocity ratio is consistent with previous observations.
