| Abstract: | This paper summarizes the major activities of study on wind buffeting noise of vehicles during past two decades.Firstly,the harm and mechanism of wind buffeting noise has been described.Then the CFD simulation of wind buffeting and its achievements are mainly presented,and four steps of CFD simulation are summed up on the foundation of the researches.Subsequently,the control and suppression of wind buffeting has been put forward,and five successful attempts of noise reduction are enumerated.Lastly,the future work is forecasted,and it is hoped that more researchers pay attention to it. |
