Bulletin of JSME, 1964 Continuing from Part 1, the authors tried to explain the mechanism of flow fluctuation in the axial-flow fan, particularly of the component which has the frequency of (NZ)/60 c/sec. The total pressure fluctuation in the neighbourhood of the fan wheel is calculated according to : first, the potential theory and, then the results of the experiment of ...
