Study on Wake Roll-Up Behavior Behind Wings In Close Proximity to the Ground Han, Cheol-Heui; Cho, Jin-Soo;
A numerical simulation of wake behavior behind three-dimensional wings in ground effect is done using an indirect boundary element method (Panel Method). An integral equation is obtained by applying Green`s 2nd Identity on all surfaces of the flow domain. The AIC is constructed by imposing the no penetration condition on solid surfaces, and the Kutta at the wing`s trailing edge. The ground effect is included using an image method. At each time step, a row of wake panels from wings` trailing edge are convected downstream following the force-free condition. The roll-up of wake vortices behind wings in close proximity is simulated.
