Aerodynamic and Noise Characteristics of a Multi-Blade Centrifugal Fan
The effects of a volute angle of scroll casing and a groove on the suction surface of blades were investigated relating to the characteristics of aerodynamics and noise of a multi-blade centrifugal fan with forward swept blades. It was shown that in the aerodynamic characteristics, the optimal volute angle existed between 4.8 and 7.2 degrees, and in ...
