Abstract
The motivation behind the present investigations is the alleviation of vortex wake hazard. The present paper contains a 3-D computational analysis of the trailing wake vortices generated by notched (rectangular) wings, at a chord-based Reynolds number of 5.34 x 10 4 . Various wing configurations were tested to determine the quantitative and qualitative effects of wing geometries on vortex dynamics. Two sets of computations were conducted up to 80 chord lengths downstream from the tip region. The first set used the conventional and notched-wing geometries for correlation of experimental and computed results. The second set of simulations concentrated on the development and testing of new wing designs. Wing geometries combined multiple tip (triangular/ogee) forms with the original notch design. The nature of vortices was classified in terms of their location, strength, and trajectories. Flow data were analyzed within these categories, at different crossflow planes behind the trailing edge
