The embodiment of the invention discloses a numerical simulation method, a device, a computing device and a storage medium for generator wind noise. The numerical simulation method for the vehicle generator wind noise utilizes the slip grid technology based on the established three-dimensional model of the generator, the sliding surface of a rotating domain and the sliding surface of a static domain are completely overlapped, the calculation error of the sliding grid technology at the interface is greatly reduced, therefore, the fluid grid to be calculated based on this can accurately calculate the flow field parameters of the vehicle generator, which provides data support for further accurate calculation of wind noise. 本发明实施例公开了种车用发电机风噪的数值模拟方法、装置、计算设备和存储介质，该车用发电机风噪的数值模拟方法，通过在建立的发电机的三维模型的基础上，利用滑移网格技术，将旋转域滑移面和静止域滑移面完全重叠，大大减少交界面处的滑移网格技术的计算误差，从而在此基础上建立的待计算流体网格能够较为精确地模拟计算车用发电机的流场参数，为进步地精确计算风噪提供了数据支撑。
