User's guide for RFPBRN, a one-dimensional transport and stability code

Abstract

RFPBRN is a one-dimensional, Lagrangian mesh, transport and stability code for Reverse Field Pinch reactors. The code employs the quasi-static approximation (ignores the inertial terms in the momentum transport equation) to follow the evolution of a plasma on a resistive time scale. The transport equations used are particle transport, energy transport and field diffusion. The model has three fluids (ions, electrons and alphas), two temperatures (ions and alphas are assumed to immediately equilibrate), and two field components (toroidal and poloidal).
