Abstract

A FORTRAN program based on a theoretical model for predicting the evaporation process of liquid fuel sprays in diesel engines is presented. The injected liquid fuel is assumed to break up into droplets in a high pressure, high temperature environment, just as encountered in a diesel engine cylinder. The complete 'history' of the droplets is described by the present program, following their motion as well as the heat absorption and evaporation mechanisms. The theoretical model is based on Newton's Second Law of Motion and the equations expressing the heat and mass balance between droplets and surrounding gas. Accurate correlations are taken into account for the prediction of Sauter Mean Diameter and the thermodynamic and transport properties of fuel.
