Summary:

AbstractThe results of the numerical characterization of the hydrodynamics of Soybean Oil Methyl Ester (SME) fuel spray using a spray model based on the moments of the droplet size distribution function are presented.A heat and mass transfer model based on the droplet surface-areaaveraged temperature is implemented in the spray model and the effects on the SME fuel spray tip penetration and droplet sizes at different ambient gas temperature (300 K to 450 K) and fuel temperature (300 K to 360 K) values are evaluated.The results indicate that the SME fuel spray tip penetration values are insensitive to variations to the fuel temperature values but increase with increasing ambient gas temperature values. The droplet size values increase with increasing SME fuel temperature. The fuel vapor mass fraction is predicted to be highest at the spray core, with the axial velocity values of the droplets increasing with increases in the SME fuel spray temperature.These results agree with those obtained from previously published experimental data and numerical results from a KIVA-3V code, though the magnitudes of the changes observed from the model are not as pronounced
