摘要

为探究平面射流对汽车天窗风振噪声的降噪机理，使用大涡模拟对带有平面射流的现代简易车厢模型进行数值仿真，分析了射流参数改变时平面射流的降噪效果变化。结果表明，添加平面射流后脱落漩涡的运动轨迹发生变化，车厢内的压力波动降低，风振噪声得到抑制；更大的射流速比和射流开口宽度能带来更好的降噪效果；不同射流角度下的降噪效果不同，降噪效果最好的射流角度区间约为110°-130°；探究了射流参数、射流轨迹与降噪效果之间的关系，为平面射流降噪装置的开发设计提供参考。

Abstract

In order to explore the noise reduction mechanism of plane jet on the vehicle sunroof buffeting noise, the Hyundai Simple Model with plane jet was numerically simulated by LES, and the noise reduction effect of plane jet was analyzed when the jet parameters are changed. The results show that after adding the plane jet, the motion trajectory of the shedding vortex changes, the pressure fluctuation in the cabin is reduced, and the buffeting noise is suppressed; the larger jet velocity ratio and jet opening width can bring better noise reduction effects; the noise reduction effect is different under different jet angles, the jet angle with the best noise reduction effect is about 110°-130°; the relationship between jet parameters, jet trajectory and noise reduction effect is explored, which provides a reference for the development and design of plane jet noise reduction device.
