      다국어 초록 (Multilingual Abstract)

      This paper describes the flow field analysis of an automobile with crosswind effects of 15˚, 30˚, 45˚ and 60˚ of yaw angles. The governing equations of the 3-D 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 computated surface pressure coefficients have been compared with experimental results and a good agreement has been achieved. The A- and C-pillar vortex and other flow phenomena around the ground vehicle are evidently shown. The variation of aerodynamic coefficients of drag. lift. side force and moments with respect to yaw angle is systematically studied.
