Abstract
To solve the buffeting problem of a SUV at low speed, the transient CFD simulation with LES model is run to get the buffeting frequency and Sound Pressure Level (SPL) at the front passenger’s ear sitting in the SUV with sunroof full open. The simulation results show that there is buffeting problem for the SUV. Then optimization of the sunroof spoiler is made and CFD simulation shows that SPL at the front passenger’s ear decreases by 9 dB. Subjective and objective road tests show that there is no buffeting problem with the optimized sunroof spoiler.
