One-liquid MHD model of plasma evolution in a tokamak

An MHD model of the tokamak plasma evolution with taking into account the plasma inertia is described. The plasma inertia account means the account for electric potential nonuniformity on a magnetic surface for the ideal plasma. The plasma drift in the field of the potential leads to variation of the plasma major radius without disturbances of the magnetic field. The plasma resistance is taken into account too. The model is applied to evolution of the plasma heated by high frequency radiation
