A multiscale model for an improved description of radial particle transport in large-scale plasmaedge simulations for tokamak fusion devices is presented. It includes the effects of mesoscaledrift fuid dynamics on the macroscale profiles, the macroscale quantities defining the local equi-librium state for the calculation of the mesoscale processes. The realization of the multiscalemodel in form of the coupled code system B2-ATTEMPT is outlined. A procedure employedto efficiently determine the averaged mesoscale terms using a nonparametric trend test, theReverse Arrangements Test, is described. Results of stationary, self-consistent B2-ATTEMPTsimulations are compared to prior simulations for experiments at the TEXTOR tokamak, mak-ing a first evaluation of the predicted magnitude of radial particle transport possible. |
