AbstractTurbulence is an ubiquitous phenomenon in plasmas, which usually have large amounts of free energy available to drive turbulent velocity fluctuations. A universal property of turbulence is its abilities to mix and to transport quantities. We discuss the relationship between passive particle transport due to turbulence and the turbulent plasma transport, that is the relationship between mixing and transport. Moreover the turbulent transport is often found not to be described by a transport coefficient, as Fick's law suggests and it's probability density distribution function (PDF) is often far from Gaussianity, implying sub‐ or super‐diffusive transport. For an interchange turbulence model we discuss upgradient transport and bursty transport behavior. Finally we discuss transport PDFs. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
