双吸离心通风机流场数值研究
Numerical Research on a Double Suction Centrifugal Fan
摘要
Abstract
The structural parameters of a double suction centrifugal fan are re-designed in the consideration of reducing produc-tion cost.To understand the effects of structure improvement on the fan aerodynamic performance , a research is carried out using computational fluid dynamics method .The numerical analysis of the two fan models implies that the newly designed fan is inferior to the original one in the aspect of aerodynamic performance , and the detailed flow field shows the inlet chamber and volute are responsible for the decrease of performance .Finally, some guidance on the improvement of fan aerodynamic performance is pro-posed.关键词
