Resistive pressure-gradient-driven turbulence with self-consistent flow profile evolution

Abstract
Resistive pressure‐gradient‐driven turbulence causes a modification of the average poloidal flow profile through Reynolds stress. The poloidal flow profile modification can be induced through a diamagnetic term and/or ‘‘seed’’ flow. This leads to several possible results for the steady‐state poloidal flow profile. If this profile is such that Vθ≠0 at the singular surface, there is a reduction in linear growth rate and suppression of the fluctuation. When Vθ = 0 and Vθ≠0, there is linear stabilization but the fluctuation suppression is weak.
