Driving comfort of today's middle and upper class passenger cars is an essential competition criterion. One important of such criteria pertains to interior noise. Experimental work revealed the A-post/side- window junction as an area of primary significance. Here flow separations are likely to occur causing severe fluctuating pressures on the side-window with ensuing accoustic radiation into the car interior. Moreover local flow properties are particularly sensitive towards inclined inflow typically occuring under realistic side-wind conditions. Since there is a direct proportionality between exterior surface pressures and interior noise the former may be used to judge the quality of different car-contour configurational changes. Therefore an experimental program was initated to systematically investigate the effects of different configurational parameters on the surface pressure characteristics in the side-window area for different inflow-angles (yaw-angles).
