Abstract

This paper presents the evidence for the role of turbulence-driven poloidal flow generation in the L-H transition induced by a turbulent heating pulse on the HT-6M tokamak. It is found that the poloidal flow υ_θ plays a key role in developing the electric field E_r and triggering the transition. The acceleration of υ_θ across the transition is clearly correlated with the enhancement of the Reynolds stress gradient.
