The effect of changes in plasma parameters, that are characteristic near or at an L-H transition in fusion edge plasmas, on fluctuation correlation lengths are analysed by means of drift-Alfven turbulence computations. Scalings by density gradient length, collisionality, plasma beta and by an imposed shear flow are considered. It is found that strongly sheared flows lead to the appearance of long-range correlations in electrostatic potential fluctuations parallel and perpendicular to the magnetic field. |
