Abstract
Some FTU plasma scenarios are characterised either by high electron
temperature, produced by ECRH, or high densities, by pellet injection . This
paper discusses the energy transport characteristics of these configurations
and compares them with the predictions of mixed Bohm/Gyro-Bohm model that has
been recently proposed. The Gyro-Bohm term of the model overestimate the
measured energy transport in the conditions when it becomes relevant. The Bohm
term alone seems to simulate correctly the experimental results, with
exception of the post-pellet enhanced confinement.
