Abstract
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 Ja 1 is demonstrated to be the most suitable for this from thepoint of view of its simplicity and accuracy. This model is applied to theanalysis 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.
