A Numerical Study on the Influence of Temperature on the Measurement Performance of Lead-bismuth Electromagnetic-flowmeter
Abstract
Liquid lead-bismuth eutectic (LBE) is one of the preferred materials for accelerator driven subcritical(ADS) transmutation targets and coolants in fourth-generation nuclear reactors. Due to the complex and interacting physical and chemical factors in the measurement process of LBE in high temperature operating environment, it is very difficult to control the flow and on-line calibration, resulting in the slow development of LBE flow meter technology, which hinders the fourth Generation nuclear reactor technology development. Electromagnetic flowmeter is currently recognized as one of the most suitable LBE flow measuring instruments in the world. In this paper, the measurement characteristics of LBE electromagnetic flowmeter at high temperature are numerically analyzed and studied, the influence of temperature on magnetic field strength and flow field distribution is quantitatively given, and the measurement linearity of LBE electromagnetic flowmeter is analyzed. The research conclusions provide a certain reference for the detection of lead-bismuth alloy flow parameters and the on-line calibration of LBE electromagnetic flowmeters in the nuclear industry control process.
