DESCRIPTION:Dr. Eric Serre\nUniversite Aix-Marseille\, Marseille\, F\nThe 
 external core plasma touching the last closed magnetic field surface (LCFS
 ) and the scrape-off layer governs the plasma-surface interactions and con
 trols tokamaks performances. The temperature and density pedestal of the h
 igh confinement regime (H-mode) builds up in this region and contributes t
 o more than 1/3 of the stored energy. Furthermore\, this region couples th
 e source of particles and momentum to the core plasma\, while it also coup
 les the ash and energy produced in the core to the sinks in the divertor.\
 nOur simulation effort concerns the turbulent transport mechanisms at the 
 edge that rule the interaction between the scrape-off layer and the confin
 ed plasma. The presentation will show our effort to design a family of tur
 bulent transport codes that solves fluid equations in versatile geometries
  from 2D diffusive regimes to 3D turbulent ones. Coupled to the neutral Mo
 nte-Carlo code EIRENE\, the code capabilities will be illustrated in 2D di
 ffusive regimes by preliminary investigation of density regimes and heat f
 luxes distribution in the WEST configuration\, which is a tungsten upgradi
 ng of Tore Supra to support ITER divertor design. Finally\, the parallel K
 elvin-Helmholtz like instability triggered at the core/SOL transition and 
 interchange turbulent flows for limited circular plasmas will be investiga
 ted. Such simulations should provide a better understanding of poloidal tu
 rbulence asymmetries and also to validate our codes both with respect to t
 heoretical stability results and to the well-documented experimental Mistr
 al base case.
