Abstract

In a given flow field the particle velocities are modelled as a Markov process, i.e., through the following stochastic differential equation

$${u_i} = {a_i}\left( {\operatorname{x} ,\operatorname{u} ,t} \right)dt + {b_{ij}}d{\xi _j},{\text{ }}d\operatorname{x} = \operatorname{u} \cdot dt$$
