Abstract
An interplay between fluctuation driven toroidal axisymmetric flows (convective cell modes) and resistive ballooning mode turbulence after the pedestal collapse is numerically studied by a four-field reduced MHD model in BOUT++ framework. The strong flow shear suppresses the radial transport of pressure filaments and the pressure profile in the pedestal region is partially recovered. As a result, a secondary instability is quasi-linearly excited, which yields a secondary collapse. The subsequent damped oscillation is also analysed by phase diagram analysis.
