Abstract
Efficient and fast predictive simulations of turbulent transport in the tokamak edge plasma remain a challenge and are key for preparing the operation and heat exhaust on fusion power plants. In this contribution, we present the application of a hierarchy of models to describe turbulent transport in edge fluid codes from empirical mean-field transport modelling to first principles 3D turbulent simulations. A reduced turbulent model is also presented to improve predictability of mean-field simulations. The three approaches are applied to simulate the same L-mode attached plasma on TCV. The models are compared with each other as well as with experimental measurements.
