Scientific paper

We present three-dimensional numerical magnetohydrodynamic (MHD) simulations of coronal mass ejections (CMEs) through a new solar wind model. The improved global corona contains non-ideal effects of the coronal heating and transport. We include the electron heat conduction, both collisional and collisionless, Alfven wave pressure for additional acceleration of the solar wind, and radiative cooling for the transition region. We also separate the electron and ion temperature and include the coulomb interactions to relax the temperatures. Our main objective is to study the effect of the non-ideal transport on the CME propagation and the CME leading shock front. The simulations are performed with the Space Weather Modeling Framework.
