Abstract: The simulation of spray combustion requires the modeling of turbulent, reacting multiphase flows, where the gas phase is described with the time-dependent, compressible, Reynolds/Favre-averaged conservation equ ations for mass, species, momentum and energy, together with the equations for the turbulence model. The liquid phase is governed by a stochastic formulation of the discrete droplet model, where the liquid and gas phases are treated separately. The liquid-gas interaction, as well as the species creation and depletion due to chemical reactions, are coup led with appropriate source terms in the gas conservation equations. One of the main problems in the modeling and simulation of two-phase flows , using the discrete droplet model approach, is the intrinsic dependence of the liquid-gas coupling on the spatial resolution of the gas phase equations. The objective of this research project is the development of a general method which reduces or eliminates such discretization dependencies.
