Abstract

This paper reports the investigation of flow behavior around winglets 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 clean wing and Whitcomb’s winglet at water velocity of 2.34 m/s, at Re = 2.33x106 . This paper focuses on the connections of both clean wing and Whitcomb’s winglet 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.
