Abstract
The objective of the research project was to numerically predict the characteristics of evaporating sprays in a turbulent shear layer. The calculations were performed such that the essential physical processes in spray evaporation in gas turbine combustors are adequately realized. The calculations modeled parallel experiments (ARO Contract number DAAG29-84-K-0165) carried out in a vertically down-flowing wind tunnel where a splitter plate separates two air streams having different velocities. The two air streams meet at the end of the splitter plate and give rise to a confined shear layer. A flat prefilming airblast atomizer is located at the trip of the splitter plate. A liquid spray formed at the atomizer tip evaporates in the turbulent shear layer and is convected downstream. An Eulerian description of the turbulent gas phase flow and a Lagrangian formulation of the droplet size class motion and heat and mass transfer were considered. Single phase two dimensional turbulent flow calculations in a duct were considered. (GRA)
