| 摘 要： | 本文根据均速管流量计在气(汽)液两相流测量中存在的问题,提出了利用两相流速分布规律重新确定总压孔开孔位置的改进方法。针对垂直上升圆管中气液两相流的速度分布式,具体给出了开孔位置的计算方法及结果,由此得到的均速管如被用于两相流测量,在测量精度、测量范围上都有所改善。

| Abstract: | In order to solve the problem of inaccuracy in the application of annubar to gas-liquid two-phase flow rate measurement, an improved method is proposed in this paper to determine the stagnation pressure holes of annubar according to the velocity profile of two-phase pipe flow. Based on the data mcasured in vertical upward two-phase pipe flow, the calculating method and result are given, this method can improve both the accuracy and the applicability of annubar. |
