| 摘 要： | 采用实验方法对对旋风机对旋叶轮级间流场进行了研究。在改变级间间隙和前后级转速的情况下,采用五孔探针对级间压力场和速度场进行了了测量,并对结果进行了分析。研究表明:前后级动叶加功量的分配在对旋风机的气动设计中占有很重要的地位,这种分配可以通过转速的匹配来实现;在气动设计中,应增加对旋叶轮级间间隙的控制设计。

| Abstract: | An experimental investigation was completed for studying the flow field between two contra rotating fans.A five hole probe was employed to measure the velocity field and pressure field between the two fans in case of varying their rotating speeds and the axial gap between them.The results of this study show: the work distribution between their rotor blades plays an important role in aerodynamic design of contra rotating fan and can be achieved through matching of their rotating speeds.Control design of the axial gap is also important for aerodynamic design of contra rotating fans. |
