Abstract
The theory-based Weiland transport model has been applied
to JET discharges with internal transport barriers (ITBs)
for the first time. The agreement of the modelling
results with the experiments has been found to be
comparable with the agreement of the modelling results
produced by the semi-empirical Bohm/gyro-Bohm transport
model. Weiland model overestimates the width of the ITB
and the electron temperature. There is evidence that the
density gradient in the Weiland model plays a more
important role in governing the ITB formation dynamics
for JET discharges than the suppression of turbulence by
the E*B flow shearing rate.
