PLASMA TURBULENCE - NEUTRALS INTERACTION IN THE EDGE OF TOKAMAKS
The project aims to improve the predictive nature of numerical simulations of the peripheral plasma in tokamaks and its interaction with the wall. These simulations are essential for the design and preparation for operation of experimental nuclear fusion reactors such as ITER.
The management of heat flows reaching the wall is based on the dissipation of the energy leaving the plasma by exploiting the interaction of the plasma with the neutral gas present in its periphery in order to distribute the power over the entire reactor wall.
Previous theoretical and experimental results suggest a significant coupling between the plasma turbulence phenomenon and the interaction between this plasma and the neutral gases. The simulation of this phenomenology requires these mechanisms to be treated in a self-coherent manner in the numerical code that will be developed.
