Magnetic Field Profiles in Fusion Plasmas in the Presence of Equilibrium Flow

In nuclear fusion magnetic confinement devices, equilibrium calculations for realistic systems are necessarily based on numerical solutions. In the present work, we describe some of the latest updates to the code FLOW [L. Guazzotto, R. Betti, J. Manickam and S. Kaye, Phys. of Plasmas 11, 604 (2004)] and give some applications. In this work we apply the code to both tokamak and Reverse Field Pinch (RFP) configurations. It is shown that plasma rotation can have a non-negligible effect on tokamak resonant modes, such as Neoclassical Tearing Modes, in particular by modifying the location of the resonant surface. Regarding RFPs, we show how toroidal flow reversal (detected in experiments) can be understood as an equilibrium effect, and how neoclassical effect can modify the plasma resistivity and current profiles.
