In this paper we introduce some model extensions to the energy balances of the 3D fluid Monte‐Carlo code EMC3 and study their influence on the simulation results for TEXTOR‐DED. We implemented local kinetic corrections to the classical parallel heat conductivity of electrons (heat flux limit). Depending on the DED configuration, a cooling effect in the outermost SOL region, resulting from the heat flux limit, can be observed. In addition, also the adiabatic cooling term 1 2 mnV 2 V , which was neglected before, was implemented into the energy iterations. This term causes a localized cooling of the ions in front of the wall, where the plasma is accelerated towards the first wall. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
