Influence of length of partitions on the generation of transit flow in MHD-channel

Abstract

Abstract The process of the transit flow generation in the magnetohydrodynamic channel of the pump is investigated. Its design provides for the variation of the flow-rate of the liquid metal without changing the current in the channel. The pressure in the pump channel creates by an electromagnetic force through the interaction of a longitudinal electric current with its own magnetic field. C-shaped ferromagnetic cores are put on the channel. The current generates its own magnetic field which magnetizes the cores. The total magnetic induction vector of the current’s magnetic field and the field of the cores is orthogonal to the channel plane. The arising electromagnetic force generates a transit flow through the channel which is caused by the presence of flow partitions in it. The pump is tested on the gallium circuit. The pressure drop at the locked mode and variable flow rate mode for different values of channel overlapping by C-cores and their different numbers has been measured in the experiment. The pressure drop — flow-rate characteristics of the channel are determined at different values of overlap the channel.
