The focus of this paper is the attempt to research the physic mechanism of vehicle buffeting further; to analyze the effects of the side window openness on vehicle buffeting; and to find suitable solutions for buffeting suppression, by using a developed procedure of CFD simulation with commercial software plus FFT acoustic post-processing. Two solutions are used for rear window buffeting reduction: constructing a cavity at the B-pillar; adding a dividing post on the rear window. Some perfectly results are obtained in this paper but feasibility still need discussion, so more efforts of wind tunnel testing are imperative for validating its feasibility. 收起
