一种适用于均速管测量的管内统一速度分布式

A unified velocity distribution of pipe-flow for annubar flowmeter's measurement

通过与指数分布模型的比较,得出管内统一速度分布式是相当可靠的.通过此分布式可确定均速管的新的取压点位置,与从前方法的结果相比,统一分布式确定的取压点测流量精度最高.

Compared with the exponential distribution, the unified velocity distribution of pipe flow is very reliable. Through this new velocity profile, we can get a new kind of distribution of pressure measurement points for annubar ftowmeters. Compared with the data of those previous methods, the measure precision is higher for the pressure measurement points of the unified velocity distribution.
