MAGNETOHYDRODINAMIC PUMP Russian patent published in 2009 - IPC H02K44/02 

FIELD: engines and pumps.

SUBSTANCE: invention refers to electrical engineering and can be used in atomic engineering, metallurgy and other art facilities. Said magnetohydrodinamic pump (MHD-pump) comprises a body representing two pipe sections - internal and external, covering twelve channels, narrowing from external to internal pipes. Through channels there liquid metal and current are passed. Permanent magnets generating magnetic flux in the channels are provided in-between the channels. Owing to interaction of the current passed through the channels and the flux in channels, liquid metal is exposed to electromagnetic force driving liquid metal in radial direction.

EFFECT: simplified current supply system that allows simplifying the pump design and reducing its cost due to series connection of channel segments to external current source.
