Description:
A Monte Carlo technique for the simulation of two-particle relative diffusion is developed using the Eulerian statistical properties of the turbulence. Numerical results are presented which clarify the role of interparticle velocity correlations and reveal the importance of an Eulerian parameter that is not present in Lagrangian theories of relative diffusion. Data on the absolute diffusion and meandering of a plume in a field of grid-generated wind tunnel turbulence are presented. These data are in good agreement with the Monte Carlo simulations.
