摘要
Three gyro-Bohm transport models are applied to the L mode discharges of the ITER pro file database for predictive tests of plasma confinement. All three models are based on ion temperature gradient driven turbulence but emphasize different aspects of the resulting turbulent transport. It is found that the model using the long wavelength component of the turbulence for the radial correlation length yields the predictions with the lowest overall residual error for a given database. Extrapolations for the performance of ITER are given for thr models used.
