Abstract

Anomalous transport is a paradigm for analysis of both Power Balance (PB) and Heat Pulse Propagation (HPP) in magnetically confined plasmas including so called non-local transport (NLT) phenomena (core heating as a reaction on the edge cooling). One of the alternative explanations of the NLT proposes to take into account the plasma motion caused by the perturbation of the force balance during HPP. First results of numerical modeling of the electron heat transport by the ASTRA code confirm the viability of this approach.
