An important phenomenon in three-dimensional flow over a wing is the existence of wingtip vortex. It has significant effects on the aerodynamics of flying vehicles. In this computational study, we investigate the effects of geometry of the wingtip on the structure of wing tip vortices. Here, we consider a rectangular half wing with NACA0012 airfoil as cross sec#on. The aerodynamics and flow field variables are computed at low Reynolds number below 50,000. The hazardous of wing #p vortex for other vehicles is insignificant. So, reduction in tip vortex only affects lift, drag and consequently performance coefficients of wing. This study shows that using shape geometry causes an increase in velocity and static pressure of tip vortex region. Also, we can observe a reduction in total vorticity magnitude and its components.
