On the local smoothness of some class of axi-symmetric solutions to the MHD equations
T. Shilkin St. Petersburg Department of Steklov Mathematical Institute, Fontanka 27, 191023 St. Petersburg, Russia
Abstract:
In this paper we consider a special class of weak axi-symmetric solutions to the MHD equations for which the velocity field has only poloidal component and the magnetic field is toroidal. We prove local regularity for such solutions. The global strong solvability of the initial-boundary value problem for the corresponding system in a cylindrical domain with non-slip boundary conditions for the velocity on the cylindrical surface is established as well.
Key words and phrases:
magnetohydrodynamics, axially symmetric solutions, regularity.
