Role of tip and edge geometry on vortex asymmetry

Abstract

Flow visualization studies were performed on an ogive-cylinder to investigate the flow over a delta wing at high incidence. Sharp tip and sharp edges (STSE), Ogive tip and Sharp edges (OTSE) and ogive tip and round edge (OTRE) model were considered for the study. Charge-coupled device (CCD) video cameras were used to capture the flow patterns and asymmetric lifting of the tip vortices from the wing. Investigation results suggested that both axisymmetric ogive tip and edge geometry were responsible for the phenomenon of vortex asymmetry and overall force distribution.
