Optimization of turbulence reduced model free parameters based on L-mode experiments and 2D transport simulations

Abstract : In this paper, a -E transport model is presented as a turbulence reduction tool for a typical ohmic L-mode discharge plasma in a divertor-configurated tokamak. Taking a Tokamak a configuration variable (TCV) study case, a feedback loop procedure is performed using the SolEdge2D code to acquire plasma diffusivity at the outer mid-plane. The -E model is calibrated through its free parameters with the aim of recovering the diffusivity calculated in the feedback procedure. Finally, it is shown that the model can self-consistently calculate diffusivity in the whole domain, recovering the poloidal asymmetries due to interchange instabilities.
