Diffusion in biased turbulence

Abstract
Analytical expressions were obtained for the Lagrangian velocity correlations and for the time-dependent diffusion coefficients of particle motion in divergence-free stochastic velocity fields with constant average Vd. The expressions were obtained by considering both the static and the time-dependent problems with the use of the decorrelation trajectory method.SCOPUS: ar.jSCOPUS: ar.jinfo:eu-repo/semantics/publishe
