Performance Analysis of Annular Linear Induction Electromagnetic Pump on the Change of Input Power and Frequency

Abstract

An annular linear induction electromagnetic pump (ALIP) with a mass flowrate of 20 kg/s and a developed pressure of 4 bar was designed and fabricated to test the performance of the components of a sodium-cooled fast reactor (SFR) in a sodium thermal hydraulic experimental loop. An electromagnetic pump having simple structure in terms of safety and maintenance, which is operated without contacting working sodium of strong chemical reaction property, is considered for the generation of sodium flow satisfying easy control of flow rate. In this study, sodium transport experiments in the sodium loop is performed to test the characteristic of the electromagnetic pump in the various conditions of input power and frequency. As a result, mass flowrate and developed pressure are analyzed on the change of input power and frequency, and the relationships of those are verified based on magnetohydrodynamics.
