SIMULATION OF WAKE VORTEX AIRCRAFT IN GROUND EFFECT

The problem developed in this paper is encountered in airplane aerodynamics and concernsthe influence of long life longitudinal wake vortices generated Canned Food by wing tips or by external obstaclessuch as reactors or landing gears.More generally it concerns 3D bodies of finite extension in crossflow.At the edge of such obstacles, longitudinal v
