本文研究了在液态金属回路中环形流道的电磁流量测量问题。首先,从麦克思韦电磁埸方程出发,进行了理论分析,导出环形流道横向磁埸的流量计的灵敏度公式。然后,在一条钠回路中进行了实验研究工作。理论分析的结果与实验结果吻合得较好。本文推导出的公式适于计算环形流道横向均匀磁场的电磁流量计的灵敏度。
In this paper, the problem of measuring the electromagnetic flow in the annular channel in a liquid metal circuit is studied. First of all, starting from Maxwell electromagnetic 埸 equation, a theoretical analysis was carried out to derive the sensitivity formula of the flowmeter of transverse magnetic ridges in the annular flow channel. Then, a sodium loop in the experimental study. The result of theoretical analysis is in good agreement with the experimental results. The formula deduced in this paper is suitable for the sensitivity of the electromagnetic flowmeter which calculates the uniform transverse magnetic field in the annular flow channel.
