In this paper,a brief historic review of automotive buffeting research is made,including early study from the middle of the last century,the “Buffeting Rush” period at the beginning of the new millennium and the consecutive “Hot Topic” decade in China.By searching and categorizing published papers,it is easy to recognize that computational method becomes more and more important for buffeting research.In the meantime,several commercially-available CFD software packages are compared on technical-suitability and financial-affordability for buffeting researchers.Moreover,to get better understanding of buffeting mechanism,four buffeting-related concepts in fluid mechanics are discussed.The procedure of CFD simulation for buffeting,developed in Chrysler during the “Buffeting Rush” period,is described and some examples of comparison with wind tunnel experiments are listed to validate the simulation procedure.Then,several methods are proposed for buffeting reduction based on buffeting mechanism.Finally,future perspective of buffeting research is addressed.
