Description
The velocity distribution method is a way to design the blade profile according to the average relative velocity in the impeller passage. Present research is aimed to investigate the effect of blade profile on the performance of a centrifugal fan with different velocity distribution functions through numerical simulations. The results show that compared with common arc blade, the centrifugal fan with new blade profile designed by velocity distribution method gets a higher efficiency, the relative velocity distribution along impeller passages of the new model is more uniform, and the boundary layer separation is delayed than that in the original model.
