抄録

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/s. The total pressure fluctuation in the neighborhood of the fan wheel is calculated according to : first, the potential theory and, then the results of the experiment of cascade. From these researches the following results have been obtained; (1) In front of the fan wheel, the mechanism of flow fluctuation is explained by the theory. (2) In back of the fan wheel, the mechanism of flow fluctuation is not explained by the theory, but is explained by the results of the experiment of cascade.
