Abstract
One-particle Monte Carlo simulations of relative diffusion in LSa are modified to account for interparticle velocity correlations both at the source and along the particle trajectories. The interparticle correlations are calculated directly from the Eulerian space-time velocity autocorrelation function. Since the particle trajectories are coupled, this is referred to as a two-particle model. Results from these two-particle simulations are compared to our previous one-particle results to determine the importance of the interparticle correlations downwind of the source. The models are evaluated by comparison with new wind tunnel data on the absolute diffusion and meandering of a plume in a field of grid-generated turbulence. (ERA citation 11:001283)
