Non-diffusive transport in the tokamak edge pedestal

W.M. Stacey, R.J. Groebner, T.E. Evans2012年被引用 17Nuclear FusionIF 3出版社

There are (at least) two classical mechanisms for non-diffusive transport in the edge plasma: (i) particle 'pinch' velocities due to forces such as V × B and Er; and (ii) outward drifts due to ion-orbit loss and X-transport. A theoretical development for the treatment of these non-diffusive transport mechanisms within the context of fluid theory is assembled and applied to several DIII-D discharges in order to investigate the importance of these non-diffusive transport mechanisms in the edge pedestal. Several interesting insights emerge from this investigation.
