Abstract
An empirical model for anomalous transport in tokamak, supplemented by the proper boundary conditions, has been developed and applied to four different types of JET discharges: ELM-free hot-ion H-mode, L-mode, ELMy H-mode and discharges with optimized magnetic shear. The results of the numerical modelling show that the model gives quite reasonable agreement with experiment in a wide range of plasma parameters and operational regimes. Moreover, they reveal some important generic features of plasma transport which are model independent.
