采用探针测定断面流时,所产生的误差存在着取压部尺寸和有限取压孔间距离方面的原因,这就使得要想正确地测定紧靠旋转叶轮后那种大梯度的流动变得非常困难。本论文提议采用单孔全压管旋转测定作为消除这些原因的方法,对比三孔探针的测定进行静止喷嘴喷流测定的探讨,同时探讨了适用于测定旋转流道间相对流的适宜的全压管形状以及摆动角、明确了其实用性。
When the probe is used to measure the cross-sectional flow, the error is caused by the size of the pressure-extracting portion and the distance between the limited pressure-receiving holes. This makes it necessary to accurately measure the large-gradient flow immediately after the rotating impeller very difficult. In this paper, we propose a single-hole total pressure tube rotation measurement as a method to eliminate these reasons, compared to the determination of three-hole probe nozzle jet measured stationary, and discussed suitable for measuring the relative flow between the rotating flow channel is appropriate Pressure tube shape and swing angle, clear its practicality.
