The analysis of gas-droplet flows is complicated by the need to account for the mass, momentum, and energy coupling between phases. The concept of regarding the droplet phase as a source of mass, momentum, and energy to the gaseous phase is described and incorporated into a computational model. A steady two-dimensional spray-cooling problem is analyzed to illustrate the applicability of the model. The predicted temperature and velocity flow field for the gas and droplet phase aptly illustrate the capability of the model to treat the complex phenomena associated with multiphase flows.
