Predictive transport simulations of jet L and H mode gyro-radius scaling experiments

摘要

Predictive transport code simulations of gyro-radius scaling experiments have been performed using experimental data from JET profile databases. Both L mode and H mode discharges are considered. self-consistently derived steady profiles of electron and impurity density, temper- atures and heat diffusivities are compared with the experimental profiles. The simulations are based on a first principle gyro-Bohm transport model for ion temperature gradient(ITG)modes, impurity modes and collisionless trapped electron(CTE)modes. In the good confinement region, the experi- mental profiles as well as the transport scalings are well reproduced by the simulations.
