Blade Optimization of Multi-Blade Centrifugal Fan: Experimental and simulation study
Abstract To overcome the technical challenges of the multi-blade centrifugal fan, such as low efficiency and insufficient total pressure, the single-arc blades of the fan were optimized and replaced in this study. The flow field of the multi-blade centrifugal fan with a single-arc blade and an airfoil blade was simulated and compared using ...

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 ...
