2411 Influence of Solidity on the Total Pressure Characteristic of a Multiblade Fan
Details
In this study, influence of solidity on total pressure of a multiblade fan was analyzed. In the analytical theory, a pressure drop caused by a biased flow along the circumferential path of the impeller was proposed. The total pressure of the fan based on the theory could be estimated with a reasonable validity. When the solidity of the impeller was small, the total pressure of the fan became high. It was experimentally proved the influence of the slip factor on the total pressure of the fan was greater than the total fluid loss.
