High-efficiency dc electromagnetic pumps and flow couplers for LMFBRs. Final report

Magnetohydrodynamic power generation, electromagnetic pumps, heat pipes, and thermionic convertors

“…Efficiencies on the order of 701 have been measured, and predicted efficiencies on the order of 80% are attainable with insulating-sidewall ducts (Refs. [34][35][36].…”

“…7, the two flows are thus coupled together, and hence the device is referred to as a "flow coupler" (Refs. 36,37). The local generation of the current enables lower voltages and higher currents to be used than would be possible with an external supply.…”
