Translated title of the contribution: Numerical Analysis of Automotive Wind Noise

    Research output: Contribution to journalArticle

    Abstract

    Wind noise radiated from the side-window and the door mirror mounted on a vehicle was computed using Lighthill's acoustic analogy. The flow fields were calculated by the well established finite-difference method with an overlapped grid technique. Computed pressure fluctuation on the door mirror surface was compared with the measured one. It was found that the pressure fluctuation as the noise source was predicted with good accuracy. Then, the shape modification to reduce the wind noise was performed based on the visualized surface streamline and noise sources. Consequently, it was confirmed that the wind noise was reduced.
