中文摘要：
针对高温气流中燃料液滴的受热蒸发过程,以正十二烷液滴为例,建立了考虑液滴受热膨胀、表面张力及气流热物性变化的分析模型。采用移动网格法,并通过温度插值减小网格移动产生的偏差,编制了计算程序。在与文献结果对比验证的基础上,数值模拟了高温对流环境中的液滴蒸发过程;探讨了高温气流加热条件下,液滴表面张力变化对液滴蒸发的影响。结果表明,是否考虑液滴表面张力及其随温度变化,对液滴内压和蒸发过程的影响不大。
英文摘要：
For the heating and evaporation of a single fuel droplet in high temperature airflow,an analytical model was established.The n-dodecane droplet was taken as an example to consider the thermal expansion,the surface tension,the thermophysical properties of airflow and their variation.By employing the mobile mesh method and using temperature interpolation to decrease the deviations caused by the mesh movement,a computer code was developed.After comparing with relevant results in the references,the droplet evaporating in a high temperature airflow was simulated,and the effects of surface tension on droplet evaporation under the heating of high temperature airflow was discussed.The results show a small influence of surface tension on the interior pressure and evaporation of the droplet.
