Recently, a turbofan with the higher flow rate and the higher pressure than the present one is required for the usage to such a complicated plumbing as a car washing machine. In addition, it is also important to establish the design method for the noise reduction of a turbofan. In this study, the aerodynamic performance of a turbofan including the noise reduction was developed by increasing the outlet angle of the impeller. In order to examine the effects of the improved performance and the noise reduction, both the distribution of relative velocity and its fluctuation in the outlet flow were investigated.
