Incorporating Turbulence Transport in the CRONOS MHD Framework — •Tobias Wiengarten and Horst Fichtner — Theoretische Physik IV, Ruhr-Uni Bochum

We will present recent advances in extending our state-of-the-art MHD code CRONOS to account for a description of the solar wind turbulence levels. The equations for these small-scale fluctuations are coupled with those for the large-scale solar wind quantities. Therefore, a self-consistent treatment of turbulence generation (e.g. via shear streams) on the one hand, and of solar wind heating via dissipation of turbulence on the other hand, is introduced. We validate our implementation by comparing with previous models before applying the model to CMEs. Our model provides the essential parameters required for Cosmic Ray transport models in the heliosphere.
