摘要

The effects of the magnetic and ExB rotation shears on the thermal ion transport in advanced tokamakrnscenarios are analyzed through the predictive modelling of the evolution of internal transport barriers. Such arnmodelling is performed with an experimentally validated L-mode thermal diffusivity completed with a semiempiricalrnshear correction which is based on simple theoretical arguments from turbulence studies. A multimachinerntest of the model on relevant discharges from the ITER Data Base (TFTR, DIII-D and JET) is presented.
