Abstract

Reversed field pinch equilibria have been numerically studied on the basis of a set of stationary dissipative MHD equations, where mass, momentum and energy conservation, Ohm's law and perpendicular heat transport are included. Moreover, an effective dynamo electric field ε is taken into account. The equilibrium magnetic field B, plasma temperature T and pressure p, as well as some associated fields are determined consistently by this system. Two types of dynamo model ε = α·B, with α either a scalar (isotropic-α model) or a tensor (symmetric hyperbolic tensor-α model), have been used and are discussed. The results are found to be in good agreement with the experimental measurements.
