To predict heat deposition on plasma-facing components of current tokamaks and future reactors, a major effort is being made to develop codes capable of modeling turbulent transport in the edge plasma. The understanding of the physical processes, the experimental study and the modeling of the heat extraction is one of the great challenges of the research on the magnetic fusion, and in particular for the imminent start of ITER.
For many years, the laboratory has been developing innovative approaches in the field of fluid models through the SOLEDGE3X code family recognized today at the international level. The modeling of transport perpendicular to the magnetic field lines is a key issue for moving towards predictive simulations. The team recently proposed an original fusion approach based on a two-equation model which considerably reduces the number of free parameters of the model, and therefore increases its predictive capacity.
As part of this PhD thesis, we will be interested in the integration of this model in the latest version of SOLEDGE3X, based on a high-order finite element approach, whose mesh discretizes with precision the plasma facing components of any complexity. At the same time, the code arriving at a level of maturity allowing confrontation with experimental measures, we will develop and integrate synthetic diagnostics which model the real diagnostic and simulate its signal. Given the plasma parameters from the simulations, we can unambiguously calculate the diagnostic signals and compare them directly with the experimental measurements from WEST operated by CEA at Cadarache.
This thesis project is therefore placed in an effort to compare numerical modeling, to assist in the interpretation of experimental measurements and to validate codes. This work will be in collaboration with the Research Institute for Magnetic Confinement Fusion of CEA Cadarache with which the team has been developing for many years SOLEDGE3X, and which operates the WEST tokamak whose mission is to study the physics of the plasma wall interactions for the preparation of ITER.
