Abstract
New numerical evidence for a transition to hard turbulence in 2D Boussinesq convection is presented. These 2D simulations agree with some, but not all, experimental results for the scaling properties of 3D hard turbulence. The transition to 2D hard turbulence, as measured by a change in the Nusselt-Rayleigh scaling law, coincides with a gradual change in the velocity probability distribution from Gaussian to exponential form and with the development of a ‘‘well-mixed’’ central region.Keywords
