Theory of 'strong' turbulence - Application to the ion acoustic instability

Creators

Description

In this thesis, we apply the techniques recently developed in the theory of turbulence to study the evolution of the current-driven ion acoustic instability. We present a method allow to describe analytically and with a self-coherent manner the dynamic of the deformation of the distribution function of particles in the same time as the evolution of the turbulent energy. We have also discerned the saturation mechanisms of the instability as well as their domain of validity. (author)

Abstract (French)

Dans cette these nous appliquons les techniques recemment developpees dans la theorie de la turbulence a l'etude de l'evolution de l'instabilite acoustique ionique, generee par un courant de derive electronique. Nous presentons une methode permettant de decrire analytiquement et d'une maniere autocoherente la dynamique de la deformation de la fonction de distribution des particules en meme temps que l'evolution de l'energie turbulente. Nous avons ainsi discerne les differents mecanismes de saturation de l'instabilite ainsi que leur domaine de validite. (auteur)
