Deterministic Ratchet Transport of Impurities in Fluids

International Journal of Bifurcation and Chaos
This paper investigates unbiased directed transport, known as the ratchet effect, within a system coupled to a fluid modeled by the bailout embedding technique. The system dynamics under the fluid influence are described by a four-dimensional mapping governed by parameters such as dissipation ([Formula: see text]), ratchet kicking (K), and the ...

Impurity transport in detached plasmas

Plasma Physics and Controlled Fusion, 1989
Transport of metallic impurities in the plasma edge was compared for normal and detached Tokamak plasmas. A neo-classical model, valid for a dirty plasma in the Pfirsch-Schluter regime, was used to calculate the impurity flux terms. Changes in the edge density and temperature profiles, characteristic of detached discharges, were seen to greatly ...

Impurity transport at the plasma edge

Journal of Nuclear Materials, 1990
Abstract Of the three major links in the chain connecting plasma edge conditions to central impurity levels, that is, (a) production (b) edge transport (c) central transport, edge transport is the weakest link in that it is the most complex, least understood and hardest to measure directly.

Analysis of classical impurity transport

Nuclear Fusion, 1976
This work is an application of Braginskii's classical theory of particle transport to partially ionized plasmas in cylindrical geometry or toroidal geometry in the Pfirsch-Schluter regime. Particular attention is given to the steady state, for which density and flux distributions are determined, and the re-cycling phenomenon is analysed.
