ABSTRACT

The flow behavior around Whitcomb winglets were investigated using experimental approach and numerical study. The experimental approach uses PIV (Particle Image Velocimetry) while the numerical study uses FLUENT. The investigation was made for a Whitcomb’s winglet at water velocity of 2.34 m/s, at Re = 2.33×106 and a clean wing also at the same configuration. This paper focuses on the connections of both and Whitcomb’s winglet and a clean wing and the formation of vortex around their winglets. From this investigation, it can be said that the vortex moves in a circular motion, from the bottom part of a winglet, which is the higher pressure part to the upper part of the winglet, which is the lower pressure part of the wingtip device. From this investigation, it was proved that the Whitcomb’s winglet produced better results compared to the clean wing in terms of the vorticity produced, thus reducing the induced drag.
