The mixing of passive scalars of decreasing diffusivity, advected in eachcase by the same three-dimensional Navier-Stokes turbulence, is studied. Themixing becomes more isotropic with decreasing diffusivity. The local flow inthe vicinity of steepest negative and positive scalar gradients are in generaldifferent, and its behavior is studied for various values of the scalardiffusivity. Mixing approaches monofractal properties with diminishingdiffusivity. We consider these results in the context of possible singularitiesof scalar dissipation.Comment: 4 pages, 5 Postscript figure
