Abstract
The feasibility is discussed of using free tubular jets of a conducting liquid in a liquid-metal MHD induction generator and in its electrophysical accessories, for producing superhigh-intensity pulsed magnetic fields, as well as for closing the gap during superhigh-current pulsed discharges through the vapor of low-melting metals. Test data are shown on the range of such tubular jets, revealing the dependence of the jet range on such factors as: the relative length of the cylindrical nozzle segment, the relative thickness of the jet tube, the companion air stream inside the liquid jet, and the conditions at the jet entrance to the receiver compartment. Noteworthy is how strongly the range of such a tubular liquid jet depends on the companion air stream and on the back pressure in the receiver.
