Abstract

In order to understand the effects of temperature, pressure and velocity on the evaporation rate of liquid hydrocarbon fuel sprays, a special fuel injector was designed that produces a monodisperse fuel spray. Droplet sizes from 70 to 150 mu m in diameter and spacings from 2 to 15 diameters can be achieved. The injector is mounted in the center of a 15 cm diameter circular duct. Preliminary results obtained at relatively dilute spray conditions for heptane are satisfactorily explained by single droplet evaporation rate expressions. A theoretical effort consisting of an Eulerian solution to the gas phase using the k- epsilon turbulence model and a Lagrangian calculation for the droplets is also described. Modeling results showing gas and liquid phase behavior are presented.
