| Abstract: | Axial-flow fan is used widely as a kind of fluid transportation machinery, and plays an important role in thefield of modern industry, so researches on the improving its efficiency have special significances. Based on the three-dimensional flow field analysis through FLUENT. the effects of decreasing the inlet flow angle on the performances ofhigh-pressure axial-flow fans were studied. Decreasing properly the inlet flow angles of the sections of blades which aredesigned according to the traditional variable circulation method can improve the efficiency. |
