| Abstract: | The research of wind buffeting noise control was currently one of the research hotspots and focuses in the automotive fields. The effectivenesses of air jet method on wind buffeting noise suppression were studied by numerical simulation analysis. The LES was used, as well as a more accurate and effective sound quality evaluation parameters was introduced. The air-jet structures of the sunroof and the right rear window were optimized respectively, and the optimal structural parameters were obtained. The simulation results show that the air-jet structures have a significant effectiveness on the suppression of wind buffeting noises. |
