Test of Core-Edge Modeling on H-mode Plasmas by Cross Validation Test in JET Tokamak

Full text: The core-edge model for predicting a pedestal formation in H-mode plasmas is developed and tested using BALDUR integrated predictive modeling code. This model expands on an anomalous core transport model (Mixed Bohm/gyro-Bohm) which is suitable for the edge of plasma by suppression due to the ωEXB flow shear and magnetic shear effects. Moreover, the stabilizer coefficients of every species (ion, electron, hydrogenic, and impurity) are calibrated with the experimental data of DIII-D tokamak. The root mean square (RMS%) analysis is used to validate the optimal point of the stabilizer coefficients in every channel. Thus, the complete core-edge model, used in predicting the pedestal formation, is confirmed accurately by cross validating with the experimental data of JET tokamak. The results show good agreement with experimental data, with the RMS average less than 20.38% in every channel (ion temperature, electron temperature, electron density, and deuterium density)
