Abstract

This paper reports on a numerical simulation of 3-D collisional drift wave turbulence. The linear instability saturates due to energy transfer to small K(2) leading to the formation of convective cells. The system tends to relax to a nonturbulent poloidal shear flow. Introducing a damping of this flow gives rise to an intermittent behaviour, where laminar periods of zero flux alternate with bursts of turbulence and large flux. The transitions occur on a time-scale shorter than linear growth times.
