摘要：

The recent version of the 3D fluid code TOKAM3X, including self-consistent variation of both electron and ion temperature, is used to investigate the properties of energy turbulent structures and heat transport. We also make a comparison with the results of the isothermal equivalent simulation. The studied regime is an L-mode-like regime where both particle and heat transport are dominated by turbulence with (turb)/(tot) > 80% and the turbulence features are found to be similar in isothermal and anisothermal models. However, the presence of a significant shear at the separatrix in the anisothermal version modifies the penetration length of turbulent structures into the scrape-off layer, and seems to trigger the appearance of a sharper gradient at the separatrix, reminiscent of the narrow feature observed in the experiment.
