Three-dimensional modelling of edge multi-component plasma taking into account realistic wall geometry

Abstract

A 3D multispecies fluid model has been implemented in the SOLEDGE-TOKAM suite of codes to address Scrape-off layer turbulent impurity transport. Zhdanov closure is used to address multi-component plasma modeling without any mass ordering or trace impurity assumption. Thanks to immersed boundary conditions, up to the wall simulations with non-axisymmetric plasma facing components are performed, in particular in the WEST configuration. A first proof of principle of interchange turbulence simulation of a Deuterium+Carbon plasma is also reported. Keywords: Edge plasma, Turbulence, Fluid modelling, Impurity transport
