The Formulation of a Helically Symmetric Magnetohydrodynamic Theta Pinch Problem

摘要

In preparation for numerical computation of dissipative magnetohydrodynamic systems with helical symmetry, a model is formulated and equations are given. After some manipulations, Maxwell's equations without displacement current are rewritten in terms of the two basic helical fluxes and the two basic input functions of time, the current in the outer conductor, and the electromotive force across the gap. One possible set of fluid equations is also given.
