Abstract

Three-dimensional (3-D) nonlinear simulations of collisional drift-wave turbulence are presented. Results for the Hasegawa-Wakatani equations (without magnetic shear) in 3-D are compared to former 2-dimensional (2-D) simulations. In contrast to the 2-D system the 3-D situation is completely dominated by a nonlinear drive mechanism. It is shown that the level of turbulence in the system in which magnetic shear is included, depends sensitively on the size of the effective Larmor radius compared with the characteristic transverse scale length of the eddies.
