Abstract
A low-specific-speed centrifugal blower with a low-solidity cascade diffuser was tested and the time variation of static pressure was measured at several locations on the side walls between cascade vanes, at the vaneles zone and at the blower intake using high frequency response pressure transducers. The time variation of flow rate was also measured at the blower intake using a hot-wire anemometer. Surge, and so called surge cycle, in the centrifugal blower were discussed based on the time histories of pressure and flow. ln addition to the data analysis of the experiments, numerical simulation was made for the system dynamic model including the effect of B-parameter and the numerical results were compared with the experimental data.
