Simulation of Unsteady Heat Transfer in the Liquid Core of the Earth with Allowance for Internal Heat Sinks

Abstract

The results of numerical simulation of unsteady convective heat transfer of an electrically conductive liquid in a spherical layer (modeling the Earth’s liquid core) under boundary conditions for a temperature of the first kind and in the presence of internal (negative) heat sinks are presented. The effect of internal heat sinks on the evolution of the structure of a liquid flow, temperature field, magnetic induction, and the distribution of Nusselt numbers in a strong magnetic field is investigated.
