Abstract
The Large Eddy Simulation (LES) approach of tracking predetermined sets of droplets via individual computational parcels is assessed for its accuracy and applicability in the dilute regime. Non-reacting particle dispersion in isotropic turbulence and turbulent temporal mixing layers are initially investigated for a range of particles in parcels and Stokes numbers. It is found that the parcel approximation may be valid for a range of Stokes numbers depending upon the particle dispersion growth rate. Spray combustion in the wake of a bluff-body and swirl stabilized combustion in a gas turbine combustor are also studied and results suggest that a limited range of particles per parcels and cutoff radius can be used safely without incurring excessive errors in the predictions.
