The effect of the vane angles on the performance of a vortex blower as well as on the noise level is investigated. A proper selection of the inlet angle α and the outlet angle β greatly improves the performance ; a combination of α=5°〜30°and β≈15°would be recommended from the viewpoint of the pressure coefficient, the efficiency and the noise level. At the same time, a simple one-dimensional theory is developed based on the angular momentum theory to predict the performance of a vortex blower. The effects of the vane angles, the splitter and the roundness in the corner of the impeller vanes are evaluated in the theory. The calculated results are compared with the experimental results.
