Abstract

Predictive transport simulations of dimensionally similar L-mode discharges have been performed using experimental data from JET profile databases. The simulations, based on a gyro-Bohm transport model for temperature gradient driven drift waves, are found to reproduce the experimental profiles of density and temperatures well. In particular, apparent Bohm-like and Goldston-like scalings of the local diffusivities are obtained as the gyro-radius is varied. The results are due to small systematic deviations from self-similarity in combination with marginal stability effects.
