Abstract

Magnetohydrodynamic (MHD) induction pumps are contactless pumps able to withstand harsh environments. The rate of fluid flow through the pump directly affects the efficiency and stability of the device. To explore the influence of induction pump settings on the related delivery speed, in this study, a numerical model for coupled electromagnetic and flow field effects is introduced and used to simulate liquid metal lithium flow in the induction pump. The effects of current intensity, frequency, coil turns and coil winding size on the velocity of the working fluid are analyzed. It is shown that the first three parameters have a significant impact, while changes in the coil turns have a negligible influence. The maximum increase in working fluid velocity within the pump for the parameter combination investigated in this paper is approximately 618%. As the frequency is increased from 20 to 60 Hz, the maximum increase in the mean flow rate of the working fluid is approximately 241%. These research findings are intended to support the design and optimization of these devices.
