Abstract
The vehicle in motion is affected by different aerodynamic forces and moments which affects the driving characteristics and other parameters of vehicle. Rapid rise in fuel cost made researchers to focus on reduction of drag. The aerodynamic forces and moments other than drag have high impact on lateral dynamic characteristics of vehicle. [1] In Baker and Reynolds in 1922 made a survey of wind induced accidents. This made study of crosswinds important. In these paper simulations are done on simple Ahmad body and modified Ahmad body for reduction of cross-wind effect on vehicles subjected to heavy cross-winds. The results obtained from the simulations are presented for different yaw angles, showing effect of various moments and forces acting on vehicle. Various pressure contours, velocity vectors etc. plots and graphs are plotted to closely understand effect of cross-winds on vehicle body. It was observed that yaw moment and rolling moment reduced which increases stability of vehicle with slight sacrifice of drag.
Keywords- Cross wind, Aerodynamics force and moments, Ahmad body.
