发展了一种使用单斜热线探针测量有回流的三维复杂流场的方法,采用旋转探针技术来实现单传感器探针的三维速度场测量,并利用热线支杆尾迹的影响来判断流动方向.使用该方法对一台低速轴流压气机的旋转失速流场进行了测量,测量结果详细地显示了失速团中流动结构,验证了该方法在复杂流场测量时简单易用、精度高,并且可以处理有回流情况的流场,对于叶轮机内部复杂流场测量有良好的实用性. A method of measuring three-dimensional complex flow field with backflow is developed by using single-oblique hot-wire probe. Three-dimensional velocity field measurement of single-sensor probe is realized by using rotating probe technology. The direction of flow is determined by the influence of wake of hot- This method is used to measure the rotating stall flow field of a low speed axial compressor, and the measurement results show the flow structure in the stalling group in detail. The results show that this method is simple and easy to use and has high precision in measuring complex flow field, And can handle the flow field with reflux condition, which has good practicability for the complex flow field measurement in the impeller.
