Turbulence in fusion plasmas: key issues and impact on transport modelling
This overview summarizes the latest developments in plasma turbulence simulations and their impact on transport modelling. The traditional approach, based on the mixing length estimate, is presented first. The self-regulation of a plasma turbulence through the formation of structures is then emphasized. It is shown that zonal flows and large-scale transport events play an important role. Also the latest results concerning the dimensionless analysis are presented. The implications for transport modelling are then assessed.
