Abstract
Resistive pressure-gradient-driven turbulence causes a modification of the average poloidal flow profile through Reynolds stress. The poloid al 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 V(the ta)'' not-equal 0 at the singular surface, there is a reduction in lin ear growth rate and suppression of the fluctuation. When V(theta)'' = 0 and V(theta)' not-equal 0, there is linear stabilization but the flu ctuation suppression is weak.
