Passive tracer in a slowly decorrelating random flow with a large mean
Passive tracer slowly decorrelating random flow large mean
2015/7/14
We consider the movement of a particle advected by a random flow of the form v + δF(x), with v ∈ Rd a constant drift, F(x) – the fluctuation – given by a zero mean, stationary random field and δ 1 s...
Scaling laws of passive tracer dispersion in the turbulent surface layer
Scaling laws passive tracer dispersion the turbulent surface layer

Abstract: Experimental results for passive tracer dispersion in the turbulent surface layer under stable conditions are presented. In this case, the dispersion of tracer particles is determined by the...
Passive tracer patchiness and particle trajectory stability in incompressible two-dimensional flows
Passive tracer patchiness particle trajectory stability two-dimensional flows

Particle motion is considered in incompressible two-dimensional flows consisting of a steady background gyre on which an unsteady wave-like perturbation is superimposed. A dynamical systems point of v...
