本文初步研究了管流旋流的衰减及其对孔板流量计测量精度的影响。涡流是由垂直平面内的双90度弯头产生的。采用双分量激光多普勒测速仪对该流场进行了测量。该管道系统对孔板流量计精度的影响已被评估，流量计放置在不同的下游位置。
The present work is concerned with a preliminary study of the decay of swirling turbulent pipe flow and its effect on the accuracy of orifice plate flow meter. The swirl was generated by a double 90 degrees elbows in perpendicular planes. The flow field has been investigated using a tow components Laser Doppler Anemometer. The effect of this piping system on the orifice flow meter accuracy has been assessed with the meter placed at different downstream locations.
