A Computational Fluid Dynamics Investigation of a Novel Ducted Winglet Design / RICHARD DAVIS

Swansea University Author: RICHARD DAVIS

Abstract

Induced drag is a crucial component of the total drag experienced by aircraft,and reducing it can improve their performance. This study investigates theefficacy of a novel ducted wingtip device in reducing induced drag.Computational fluid dynamics simulations were performed on an EmbraerERJ145 aircr...
