中文摘要: |
轴流式通风机作为使用较为广泛的流体输送机械,在现代工业领域中扮演着相当重要的角色。通过FLUENT软
件数值模拟轴流风机的三维流场,研究减小进口气流角对高压轴流风机性能的影响。在利用变环量风机设计方法所得
到的叶片基础上,适当减小叶片各截面的进口气流角可以提高高压轴流风机的效率。 |
英文摘要: |
Axial-flow fan is used widely as a kind of fluid transportation machinery, and plays an important role in the
field 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 of
high-pressure axial-flow fans were studied. Decreasing properly the inlet flow angles of the sections of blades which are
designed according to the traditional variable circulation method can improve the efficiency. |
