Numerical investigation of the flow over delta wing and reverse delta wing

Abstract This study aims to give some thoughts and initial understanding of passive wake vortex alleviation by introducing add-ons devices onto the aircraft, which are delta wing (DW) and reverse delta wing (RDW). However, as a preliminary investigation, the study has treated these devices separat...
