| Abstract: | The purpose of this study is to investigate the behaviors of fuel film e-vaporation on the wall of combustion chamber n diesel engines. A test bed for investigating the process of fuel film evaporation on the wall of combustion chamber was developed. The process of fuel film evaporation on a hot wall was studied. The effects of wall temperature, air flow velocity and air flow temperature on the behaviors of fuel film on a hot wall were also studied experimentally. A model was established to investigate the heat and mass transfer during the process of fuel film evaporation on a hot wall numerically. |
