Impurity transport in temperature gradient driven turbulence
@article{Skyman2012ImpurityTI, title={Impurity transport in temperature gradient driven turbulence}, author={Andreas Skyman and Hans Nordman and P. Strand}, journal={Physics of Plasmas}, year={2012}, volume={19}, pages={032313} }
In the present paper, the transport of impurities driven by trapped electron (TE) mode turbulence is studied. Non-linear (NL) gyrokinetic simulations using the code GENE are compared with results from quasilinear (QL) gyrokinetic simulations and a computationally efficient fluid model. The main focus is on model comparisons for electron temperature gradient driven turbulence regarding the sign of the convective impurity velocity (pinch) and the impurity density gradient R/LnZ (peaking factor…
