  1. 278. Passive scalar and magnetic field transport in potential flows
    Prof. Karl-Heinz Raedler (Astrophysical Institute Potsdam)

    It is demonstrated that the total mean-field diffusivity for passive scalar transport in a compressible fluid showing isotropic turbulence may well be smaller than the molecular diffusivity. This is in full analogy to the old finding regarding the magnetic mean-field diffusivity in an electrically conducting turbulently moving compressible fluid (e.g. Krause and Rädler 1980). For both...

  2. 279. Compressibility effects on turbulent MHD and passive scalar transport
    Prof. Nathan Kleeorin
    16/02/2011, 14:30
    The effects of compressibility (finite Mach number effect) and stratification of turbulent fluid flow on mean-field transport coefficients of magnetic field and passive scalar (number density of particles and temperature field) are studied for small and large magnetic Reynolds numbers (or small and large Peclet and Schmidt numbers) using correspondingly the quasi-linear approach and the...
