Abstract: The results of numerical simulation of heat transfer of liquid metals in a spherical layer are presented. The influence
of the orientation of the gravity vector, the magnetic interaction parameter and the Hartmann number on the flow structure,
temperature field, magnetic induction, and the distribution of local Nusselt numbers has been investigated.
Index terms: mathematical modeling, heat transfer, magneto hydrodynamics, liquid metals, heat of Joule dissipation, spherical layer.
