Drag Reduction: Design & Analysis of Vortex Generator
Ashish Domal [2] | VinayAhuja | Pankaj Ande [2]
Abstract: In initial flow simulation, Audi a4 car model is imported in CHAM PHOENICS- CFD software and tested under different speeds, then airflow, pressure and velocity value are analysed. After that in modified flow simulation, vortex generators are carefully designed and installed at the rear end of the vehicle and same cycle is repeated. After getting results from both the flow simulations, differences in aerodynamics characteristics are studied. Drag forces are calculated in both initial and modified flow simulations, to understand the effect of vortex generator i. e. to check whether drag of the vehicle is reduced or not after installing vortex generator, as ultimate aim of the vortex generator is to reduce drag properties at the rear end of the car by reducing flow separation and turbulence of air.
