The application of fluid models in studies of transport and macroscopic stability of magnetized, nearly collisionless plasmas requires closure relations that are inherently nonlocal. Such closures address the fact that particles are capable of carryi

A conforming representation composed of 2D finite elements and finite Fourier series is applied to 3D nonlinear non-ideal magnetohydrodynamics using a semi-implicit time-advance. The self-adjoint semi-implicit operator and variational approach to spa

In previous work it was shown that progress in attaining and maintaining stable mean reversed-field pinch (RFP) profiles can be made by abandoning the steady-state assumption and instead seeking solutions of the pressureless (force-free), one-dimensi

A method is developed for determining directly from experimental data the classical tearing mode stability parameter Δ′. Specifically, an analytical fit function is derived for the electron temperature fluctuations (Te) in the vicinity of a magnet
