Evaluation of gasoline evaporation during the tank splash loading by CFD techniques

This paper presents a CFD simulation of gasoline evaporation during the splash loading of gasoline tank. The volume of fluid based (VOF) interface tracking method in conjunction with a mass transfer model was used. Evaporation rate was determined by a source term at the interface. The effect of different parameters such as loading velocity, temperature and initial vapor mass fraction on gasoline lost was determined. The results show that by increasing the loading velocity, the total evaporated mass decreases. Based on CFD simulations a correlation has been proposed to evaluate the amount of gasoline losses during the fuel tank splash loading.
