【 摘 要 】

The results of numerical modeling of convective heat transfer of an electrically conductive liquid in a spherical layer are presented. The influence of the heat of Joule dissipation, the Grashof number and internal heat sources uniformly distributed in the liquid on the structure of the flow of an electrically conductive liquid, the temperature field, magnetic induction and the distribution of local Nusselt numbers are investigated when the vector acceleration of gravity is directed along the radius k the center of the spherical layer.
