Abstract

This paper describes the flow analysis of the automobile with crosswind effects of $15^{\circ},\;30^{\circ}\;and\;45^{\circ}$ of yaw angle. The governing equations of the 3-D unsteady incompressible Navier-Stokes equations are solved by the iterative time marching scheme. The Chimera grid technique has been applied to efficiently simulate the flow around the side-view mirror. The A- and C-pillar vortex and other flow phenomena around the ground vehicle are evidently shown.
