In fusion devices such as tokamaks, the achievement of good energy confinement is a key issue. The energy, particle and angular momentum transport is dominated by turbulent : Clarisse Bourdelle. Turbulence Induced Transport in Tokamaks Article (PDF Available) in AIP Conference Proceedings (1) January with 41 Reads How we measure 'reads'. In general, turbulent transport drives a plasma toward a state of turbulent equipartition, in which Lagrangian invariants are uniformly distributed. Different invariants decay with different rates, and in tokamaks the frozen-in law of particles in the poloidal magnetic field survives longer than the corresponding law for the toroidal field, assuming that the trapped particles dominate the.

The energy, particle and angular momentum transport is dominated by turbulent mechanims. To understand, model and predict temperature, density and rotation is existing and future tokamaks, a numerical tool, bridging theory and experiments, is ear gyrokinetic codes allow for detailed understanding of turbulent transport. In magnetically confined fusion plasmas like tokamaks, transport of heat and particles is dominated by turbulence. Turbulent transport models can be validated using experimental data, using a rigorous methodology and direct comparisons with turbulence measurements. While the transport models capture details of the turbulence very well, and can be used to predict steady-state temperature.

This paper is an overview of recent results relating to turbulent particle and heat transport, and to the triggering of internal transport barriers (ITBs). The dependence of the turbulent particle pinch velocity on plasma parameters has been clarified and compared with experiment. Magnetic shear and collisionality are found to play a central role. Analysis of heat transport has made progress. About this book In this new approach for a consistent transport theory in nuclear fusion processes Leslie Woods draws on over 40 years of fusion research to directly compare theoretical findings with experimental results, while taking into account recently discovered phenomena. This book is distinguished by its simultaneous focus on the fundamentals of turbulent flows (in neutral and ionized fluids) and on a presentation of current research tools and topics in these fields. Contents: Two- and Three-Dimensional Turbulence (H Tennekes) Magnetohydrodynamic Turbulence (D Montgomery) Helicity (D Lilly). This report is concerned with plasma edge turbulence and its relation to anomalous particle transport in tokamaks. First, experimental evidence of turbulence driven particle transport and measurements of the gradients of the equilibrium profiles in the Brazilian tokamaks TBR and TCABR are presented.
