内容記述 | Specific noise is a noise for base unit of flow rate and total pressure. It can be applied to estimate the overall characteristic of a fan. In this study, an analytical theory for the specific noise based on internal flow of a multiblade fan is proposed; moreover, the specific noise of the fan having an impeller with a different number of blades was discussed. The total pressure coefficient of the fan having 120 blades (MF120) became lower than the fan having 40 blades (MF40). On the other hand, the noise level of MF120 became 5.8 dB smaller than MF40 because the relative velocity was reduced by the slip. It was estimated by analyzing internal flow that the specific noise of MF120 was 4.3 dB smaller than MF40. | |||||
