Predictive simulations of impurity transport at JET

• The impact of sheared toroidal rotation on impurity transport is studied by means of predictive simulations of JET L-mode and H-mode discharges with carbon wall using the coupling between the transport codes JETTO for main ions and SANCO for impurities. The simulations are based on a fluid model for Ion-Temperature-Gradient (ITG) mode and Trapped-Electron (TE) mode driven turbulence and neoclassical transport. The fluid impurity transport coefficients are compared with gyrokinetic simulations using the code GENE. Predictive simulations of temperatures (Te, Ti=TZ) and densities (ne, nZ) are performed while the toroidal rotation is treated interpretatively.
