Abstract
The main goal of the present chapter is to investigate probabilistic and spatiotemporal characteristics of the passive tracer in a randomly moving medium with random velocity field \({\varvec{v}}({\varvec{x}}, t)\). Both, the case of compressible, and of incompressible \(({{\varvec{\nabla }}}\cdot {\varvec{v}}\equiv 0)\) media will be considered. The material is based on the authors’ paper [1]. In the previous chapter, we have investigated the passive tracer transport in randomly moving media governed by a simplified hydrodynamic model of Burgers turbulence. The full program of such investigation should include prior recovery of the statistical properties of the velocity field \({\varvec{v}}({\varvec{x}}, t)\) satisfying fully nonlinear equations of the hydrodynamic type such as the Navier–Stokes equation for an incompressible fluid, which however, is beyond the scope of this book.
