Title:

Averaged Resistive MHD Equations

Date of publication:

Sep. 1993

Key words:

resistive MHD equations, averaged method, Mercier criterion, Lagrangian, resistive interchange, local stability

Abstract:

Averaged resistive MHD equations are derived by using the Lagrangian formalism. The assumption is that the perturbation is of single toroidal harmonics on the special magnetic coordinates Jacobian of which is independent of the toroidal angle. The metrics contained in the obtained resistive equations are those appearing in the averaged equilibrium equations. The local stability conditions are also derived.
