Abstract

In this work a phenomenological model of the thermal transport caused by ion-temperature-gradient-driven turbulence is introduced. A relevant property of the model is that the thermal conductivities grow with minor radius, due to the positive dependence of the correlation length and of the inverse timescale on the ion temperature gradient. A comparison of the predicted profiles with the experimental ones of several machines is presented.
