Intermittent distribution of tracers advected by a compressible random flow
Jeremie Bec, Krzysztof Gawedzki, Peter Horvai
Multifractal properties of a tracer density passively advected by a compressible random velocity field are characterized. A relationship is established between the statistical prop…
Sticky behavior of fluid particles in the compressible Kraichnan model
Krzysztof Gawedzki, Peter Horvai
We consider the compressible Kraichnan model of turbulent advection with small molecular diffusivity and velocity field regularized at short scales to mimic the effects of viscosit…
Lagrangian dispersion in Gaussian self-similar ensembles
Marta Chaves, Krzysztof Gawedzki, Peter Horvai +2
We analyze the Lagrangian flow in a family of simple Gaussian scale-invariant velocity ensembles that exhibit both spatial roughness and temporal correlations. We show that the beh…
