Effects of collisional ion orbit loss on tokamak radial electric field and toroidal rotation in an L-mode plasma
Hongxuan Zhu, T. Stoltzfus-Dueck, R. Hager +2
Ion orbit loss has been used to model the formation of a strong negative radial electric field in the tokamak edge, as well as edge momentum transport and toroidal rotation.…
Effects of collisional ion orbit loss on neoclassical tokamak radial electric fields
Hongxuan Zhu, T. Stoltzfus-Dueck, R. Hager +2
Ion orbit loss is considered important for generating the radially inward electric field in a tokamak edge plasma. In particular, this effect is emphasized in diverted tokama…
Wave-kinetic approach to zonal-flow dynamics: recent advances
Hongxuan Zhu, I. Y. Dodin
Basic physics of drift-wave turbulence and zonal flows has long been studied within the framework of wave-kinetic theory. Recently, this framework has been re-examined from first p…
Theory of the tertiary instability and the Dimits shift within a scalar model
Hongxuan Zhu, Yao Zhou, I. Y. Dodin
The Dimits shift is the shift between the threshold of the drift-wave primary instability and the actual onset of turbulent transport in magnetized plasma. It is generally attribut…
Theory of the tertiary instability and the Dimits shift from reduced drift-wave models
Hongxuan Zhu, Yao Zhou, I. Y. Dodin
Tertiary modes in electrostatic drift-wave turbulence are localized near extrema of the zonal velocity with respect to the radial coordinate . We argue that these modes c…
Solitary zonal structures in subcritical drift waves: a minimum model
Yao Zhou, Hongxuan Zhu, I. Y. Dodin
Solitary zonal structures have recently been identified in gyrokinetic simulations of subcritical drift-wave (DW) turbulence with background shear flows. However, the nature of the…
