Abstract

A significant problem of fuel cell vehicles is high-frequency noises caused by air support system, and the air compressor generates the maximum noise. The vortex blower is adopted as the compressor. The noise of the vortex blower at the front and outlet was measured and analyzed under steady and unsteady conditions. It is concluded that there are discrete peak frequencies and the 10 times, 42 times, 84 times frequencies are the most significant. By simulation of interior pressure fluctuation of the vortex blower using Fluent, the cause of the harmonic frequencies is explained.
