Abstract

The document contains the slides to a presentation held at the 11th European Fusion Theory Conference. It covers the following topics:
Particle and heat fluxes versus density and temperature gradients?
Turbulence EquiPartition Theory (fluid)
Traditional formulation
TEP and thermodiffusion terms are additive in particle flux
Raises several questions:
- what is the thermodynamical meaning of TEP terms?
- does Onsager symmetry principle apply?
- implications for the heat flux
- are pinches consistent with the second principle?
-> calculate entropy production rate.

Outline
- Experimental evidence of off-diagonal terms in particle flux.
- Introduction to pinch mechanisms: Turbulence
-Equipartition Theory. Extension to interchange turbulence: curvature and thermodiffusion.
- Entropy production rate: fluid and kinetic theories.
- Examples: particle (e/D) and impurity transport.
