Montgomery, D. C.

Our recent activity has been focussed on the following three subjects: turbulent relaxation processes in driven, dissipative MHD fluids in a dc magnetic field and the relaxed steady states that result; variational principles, particularly those of the minimum-dissipation-rate variety, as an analytical predictor of the properties of the relaxed states; and the inclusion of variable mass density and compression in the evolution of MHD turbulence. These areas represent for us sensible abstractions of the problems involving the principal uncertainties for tokamaks, reversed-field pinches, and other current-carrying confinement devices, as well as being of great importance for solar-terrestrial MHD processes. We now outline briefly each of these areas.
