Abstract
Приведены результаты численного моделирования неустановившегося конвективного теплообмена и магнитной гидродинамики электропроводящей жидкости в концентрическом сферическом слое. Исследовано влияние малых значений магнитного числа Рейнольдса и диссипации джоулева тепла на эволюцию структуры течения жидкости, поле температуры, магнитной индукции и распределение чисел Нуссельта.
The results of numerical simulation of transient convective heat transfer and magnetohydrodynamics of an electrically conductive fluid in a concentric spherical layer are presented, taking into account Joule heat dissipation. The effect of small values of the magnetic Reynolds number and dissipation of joule heat on the evolution of the fluid flow structure, the temperature field, magnetic induction, and the distribution of Nusselt numbers is studied.
