摘要：An improved multi-component vaporization model was developed and applied to predict the vaporization characteristics of a fuel droplet under oxygen-enriched and exhaust gas recirculation (EGR) conditions in this study. The model was constructed including an improved enthalpy diffusion sub-model, a corrected Stefan flow velocity, and temporal variation of thermal physical properties. The computational results were validated with the experimental data and satisfactory agreements between the predictions and measurements can be achieved. The effects of O-2, CO2 concentration, and EGR on the vaporization rate of fuel droplet in various ambient temperature and pressure conditions were investigated.
