摘要
采用计算流体力学(CFD)技术对某电站多声路超声波流量计积分误差进行分析,获得了压力管道水流分布,为多声路超声波流量计的声路选择、精度分析提供了理论依据与新的方法,并对影响精确度的其他因素进行分析,最终确定系统的精确度。
Computational fluid dynamics （CFD） technology is adopted for the multi-paths ultrasonic flow measurement accuracy analysis of a hydropower station. The distribution of fluid in the penstock is obtained. New theoretical methods are offered for precision analysis and selection of ultrasonic channels. Other factors influencing precision are also analyzed. Finally,the accuracy of the system is confirmed.
