Abstract

This document contains the slides to a presentation held at the 2nd IAEA Technical Meeting on the Theory of Plasma Instabilities. The motivations of the talk were:
- Strong discrepancies between kinetic and fluid descriptions of turbulence: Linear thresholds; non linear thresholds.
- New type of non collisional closures: Non local; non dissipative
The outline of the talk:
Standard closure assumes weak departure from local thermodynamical equilibrium -> small number of moments required
Aim: Compare kietic and fluid approaches (linera and non linear) in a simple turbulence problem:
- Same instability (2D intercharge)
- Same numerical tool
Closure based on entropy production rate
