Theory-based transport modeling of TFTR

Abstract

Transport simulations of TFTR temperature and density profiles have been carried out with the Nordman-Weiland transport model for η_i and trapped electron modes (including impurities and finite Larmor radius effects) combined together with resistive ballooning mode and neoclassical transport models. The Nordman-Weiland model is combined together with models for transport driven by pressure gradients to compute the coefficients for the transport of ion heat, hydrogen ions, and electron heat. The predictions of this model are compared with the experimentally observed profiles for TFTR L-mode and supershot plasmas.
