摘要

对现有的气泡生长模型进行了综述，并展望了这些模型在水/燃料复合液滴充气/微爆炸研究中的应用前景。从简洁性和准确性的角度来看，在Ja比1的极限下Chernov等模型的简化版本是最适合的。该模型应用于500 ~ 1000 K温度下空气中水/正十二烷复合液滴膨化/微爆炸时间的分析。这些液滴的膨化/微爆炸时间和气泡生长时间是根据在托木斯克国立研究理工大学进行的实验得到的。该模型预测的气泡生长时间与实验结果相当接近。而且，这些时间的值非常接近由基础方程的直接数值解所预测的值。

Bubble growth in composite water/fuel droplets: Effect on timing of their puffing/micro-explosion

The existing models of bubble growth are reviewed with a view to their possible application to the study of puffing/micro-explosion in composite water/fuel droplets. A simplified version of the Chernov et al. model in the limit of

is demonstrated to be the most suitable for this from the point of view of its simplicity and accuracy. This model is applied to the analysis of timing of puffing/micro-explosion in composite water/n-dodecane droplets placed in air at temperatures varying from 500 to 1000 K. The times to puffing/micro-explosion and bubble growth times for these droplets were obtained based on experiments performed at the National Research Tomsk Polytechnic University. The bubble growth times predicted by this model are shown to be reasonably close to the experimental results. Also the values of these times are very close to those predicted by the direct numerical solution of the underlying equations.
