INFLUENCE OF BOUNDARY CONDITIONS FOR THE RADIAL COMPONENT OF MAGNETIC INDUCTION ON HEAT EXCHANGE OF LIQUID IN A SPHERICAL LAYER

The article presents the results of numerical simulation of unsteady-state heat exchange of an electrically conducting liquid in a spherical concentric layer with account for the Joule heat dissipation. The infl uence of boundary conditions for the radial component of magnetic induction on the evaluation of heat exchange, hydrodynamics, magnetic induction, and the Nusselt number distribution at small values of the magnetic Reynolds number was studied. The values of the magnetic Reynolds number at which a change in the intensity of heat exchange occurs on the liquid layer surface are determined
