Single-helicity states in compressible magnetohydrodynamics simulations of the reversed-field pinch with nonuniform resistivity
Using a magnetohydrodynamics numerical code that includes the description of density and pressure evolution and anisotropic thermal conductivity, it is shown that single-helicity states in the reversed-field pinch (RFP) configuration are obtained when the resistivity has a radial profile sharply increasing close to the wall. In contrast, a uniform resistivity produces multiple-helicity states. ...
متن کامل6 On non existence of tokamak equilibria with purely poloidal flow
It is proved that irrespective of compressibility tokamak steady states with purely poloidal mass flow can not exist in the framework of either magnetohydrodynamics (MHD) or Hall MHD models. Non-existence persists within single fluid plasma models with pressure anisotropy and incompressible flows.

متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
متن کاملCalculation of resistive magnetohydrodynamics and two-fluid tearing modes by example of reversed-field-pinch-like plasma
An algorithm suitable for numerical solution of linear eigenmode problems in resistive magnetohydrodynamics MHD and two-fluid MHD models without prior approximations is presented. For these plasma models, sets of equations suitable for numerical solution are derived and the details of the algorithm of this solution are given. The algorithm is general and is suitable for solution of boundary eig...
