HEAT EXCHANGE AND MAGNETIC HYDRODYNAMICS OF A LIQUID IN A SPHERICAL LAYER AT SMALL MAGNETIC REYNOLDS NUMBERS

Results of numerical simulation of the unsteady heat exchange in a layer of an electrically conducting liquid between two concentric spheres and of the magnetic hydrodynamics of this liquid at small magnetic Reynolds numbers (Rem = 10^–1 , 10^–2 , 10^–3 , 10^–4 , 10^–5 , and 10^–6 ) and the homochronicity numbers Ho = 0.1 and 10 are presented. The infl uence of the Joule heat dissipation in this layer on the evolution of the liquid fl ow structure, the temperature and magnetic-induction fi elds, and the distributions of local Nusselt numbers in it, depending on the values of Rem and Ho, was investigated.
