Particle Simulation of Inhomogeneous Turbulent Diffusion

The dispersion of aerosols by turbulent diffusion can be modelled on a computer by following the paths of a group of particles, whose actual turbulent velocities are simulated by random movements. This particle simulation is a useful model of turbulent diffusion — as far as statistical averages are considered -, if the most important properties of the actual physical process are reproduced on the computer.
