生物乙醇和生物柴油是发展迅速且潜力巨大的两种生物燃料,在最近关于生物乙醇、生物柴油与常规柴油掺混的三组分燃料的研究中发现了许多良好的燃烧特性。然而,人们对于这种轻质+中质+重质组成的新燃料的蒸发和燃烧机理尚不清楚,其蒸发特性尚待研究。本文在建立的描述多组分液滴蒸发所需的气相模型、液相模型、气液界面耦合方程基础上,对多组分生物燃料液滴的蒸发过程进行了研究并得到液滴表面以及内部详细的组分和温度分布。
Bioethanol and biodiesel are two rapidly growing and promising biofuels that have found many good combustion characteristics in a recent study of bioethanol, biodiesel and three-component fuels blended with conventional diesel. However, the mechanism of evaporation and combustion of the new fuel with such a light weight, medium-weight and heavy-weight composition is not yet known, and its evaporation characteristics have yet to be studied. Based on the established gas-phase model, liquid-phase model and gas-liquid interface coupling equation, which describe the evaporation of multicomponent droplets, the evaporation of multicomponent biofuel droplets was studied and the droplet surface and inner Detailed composition and temperature distribution.
