Liquid metal pipe flow hydraulic resistance in a transverse magnetic field

The results of an experimental study of the effect of a transverse magnetic field on the hydraulic resistance during the flow of mercury in a round pipe with different wall conductivity are considered. The changes in the coefficients of hydraulic resistance at Reynolds numbers in the range Re = (10–40) $\cdot$ 10$^3$ and magnetic fields providing Hartmann numbers in the range Ha = 0–1800 are investigated. Pipes with different steel wall thicknesses are considered, and the effect of copper plating aimed at improving the electrical contact at the mercury-steel interface is studied.
