| 摘 要： | 综合多叶片离心风机噪音低以及长短叶离心风机气流稳定的优点,设计了一种具有大小叶片交错组合结构的多翼离心风机.采用计算流体力学方法,分别模拟了前向式和后向式2种不同叶轮形式的风机流场.通过对比发现,在相同转速和流量下,后向式风机进出口压差比前向式叶轮风机小11.8％,但功率消耗降低了24.5％,综合效率较前向式高；后向式... |

| Abstract: | Combining the advantages of low noise on multi-blade centrifugal fan and stationary gas flow on splitter blade centrifugal fan,a kind of multi-blade centrifugal fan with splitter blades was designed.By computational fluid dynamics method,the flow fields stirred with forward curved blade and backward curved blade were both simulated.By comparison,it shows that with the same revolving velocity and fluid flux,the pressure drop between inlet and outlet in backward curved blade is 11.8% lower than that in forwar... |
