Abstract
Self-consistent transport code simulations have been performed for a system of temperature gradient driven toroidal drift modes using a fluid model valid for arbitrary Ln/LB. Both an L-mode scaling for low heating power and transitions to enhanced confinement regimes for higher heating power have been obtained. In the enhanced confinement regime, a state with typically χe > χi develops.Keywords
