摘要
本文从分析压力管道水流流速分布规律出发,分别应用高斯和马尔科夫数值积分方法,得出了圆形管道多声路超声波测流流量计算、声道分布坐标及权重系数的数学模型,并用现场实测资料进行了验证。
According to the law of flow velocity distribution in penstock and by individually using the numerical integration methods of Gauss and Markov, the mathematical models for discharge calculation, path distribution coordinates and weight coefficient of multiple-path supersonic flow measurement in circular penstock are obtained, The measuring results of these models have been verified by the data got in field.
