这份报纸在对流环境基于在二之间的流动，和热和集体转移的答案分阶段执行的提高温度的空中分析简单纯微滴燃烧的熵产生率。流动地计算被为每个阶段解决各自的保存方程执行，为与 axisymmetric 模型一起的微滴变丑的财务。温度，速度和在微滴燃烧的过程的全部的熵产生率上的免费溪流空气的氧部分的效果被调查。特殊注意被给分析微滴变丑的量的效果。结果表明熵产生率由于化学反应占据产生的全部的熵的大部分，由于火焰盖住的大区域。尽管，每体积，由于热，转移和联合质量和热转移的熵产生率的大小比由于化学反应，他们盖住一个很有限的区域的有大的一份订单的大小，导致全部的熵的小部分产生了。熵产生率由于集体转移是可以忽略的。高温度和免费溪流的高速度是有益的在小雷纳兹数字的范围增加 exergy 效率(< 1 ) 从在微滴一生上的秒法律分析的观点。全部的熵产生上的微滴变丑的效果是谦虚。

英文摘要：

This paper analyzes the entropy generation rate of simple pure droplet combustion in a temperature-elevated air convective environment based on the solutions of flow, and heat and mass transfer between the two phases. The flow-field calculations are carried out by solving the respective conservation equations for each phase, accounting for the droplet deformation with the axisymmetric model. The effects of the temperature, velocity and oxygen fraction of the free stream air on the total entropy generation rate in the process of the droplet combustion are investigated. Special attention is given to analyze the quantitative effects of droplet deformation. The results reveal that the entropy generation rate due to chemical reaction occupies a large fraction of the total entropy generated, as a result of the large areas covered by the flame. Although, the magnitude of the entropy generation rate per vol- ume due to heat transfer and combined mass and heat transfer has a magnitude of one order greater than that due to chemical reaction, they cover a very limited area, leading to a small fraction of the total entropy generated. The en- tropy generation rate due to mass transfer is negligible. High temperature and high velocity of the free stream are advantageous to increase the exergy efficiency in the range of small Reynolds number （〈1） from the viewpoint of the second-law analysis over the droplet lifetime. The effect of droplet deformation on the total entropy generation is the modest.
