摘要: 介绍了钐钴永磁流量计的研制过程,包括材料选取、结构设计、运行原理及内部磁场分布状态。利用镓铟锡高温冲刷回路与商用流量计对其进行了校准比对,结果显示校准后的平均流速约为钐钴永磁流量计测量值的 1.8 倍。将校准后的结果运用于液态锂铅自然对流回路的流速测量,并与商业软件 ANSYS Fluent 模拟计算结果进行对比,二者之间的误差约为 23.3%,并对误差进行了分析。通过实验与分析,确定锂铅自然对流回路的流速范围约为 0.05~0.06m·s-1 。

Abstract:

A development process for the samarium-cobalt permanent magnet flowmeter is presented, consisting of material selection, structure design, operation principle and internal magnetic field distribution. The calibrated average velocity by the commercial flowmeter in the gallium-indium-tin high temperature scouring loop is about 1.8 times of the measured value by the samarium-cobalt permanent magnet flowmeter. The calibrated formula is applied to the velocity measurement of lead-lithium natural convection loop and compared with the simulation of commercial software ANSYS Fluent. The error between them is about 23.3%, and is analyzed. It can be determined that the velocity range of lead-lithium natural convection loop is from 0.05m·s-1 to 0.06m·s-1 through the experiment and analysis. 

Key words: Samarium-cobalt permanent magnet flowmeter, Lead-lithium liquid metal loop, Flow velocity
