Abstract

The computer models used to calculate spray combustion are strongly dependent on the evaporation rate of the fuel droplets. Due to their complexity the droplet evaporation submodels are strongly simplified. This means that an unrealistic fuel composition is used (mono- or bicomponent fuel). The gas and liquid phases are usually treated as ideal, which is invalid at the high pressures that occur in the diesel engine. To explore the effects of these simplifications in detail, a realistic model of the evaporation of a single moving fuel droplet at high pressure is developed. In this paper the differential equations with their boundary conditions are presented and their numerical solution is discussed. It is shown tha
