Comparison between JET Profile Data and the Predictions of a Transport Model Based on ITG and Trapped Electron Modes
The predictions of a reactive drift wave model for anomalous transport in tokamaks is compared with JET profile data, using two different approaches. An interpretative approach is used to compare the radial heat fluxes under approximate steady state conditions. For the considered steady states, taken from seven auxiliary heated JET discharges in various regimes, the predicted total heat flux tends to be overestimated in the inner parts or underestimated in the outer parts of the good confinement region. A predictive approach is used to compare the density and temperature profiles of five L-mode discharges. These results are in good agreement with experiments (in the good confinement region the relative errors in the temperature profiles are below or equal to 20% and in the density profile approximately below or equal to 25%). The interpretative code TRANSP is used to obtain the experimental profile data.
