Energy Balance of Puffing and Microexplosion of Two-Liquid Droplets

The results of energy analysis of the fragmentation regimes (puffing and microexplosion) of two-liquid droplets of the core-shell type are given. It is shown that using the classical energy approach to describe the hydrodynamic processes, it is possible to predict the critical (necessary and sufficient) conditions for the implementation of fragmentation regimes and their consequences. As distinct from the force approach, it is possible to estimate the discrete energies spent on evaporation, heating, fragmentation, viscous dissipation, and resistance during the motion of the fragmentation front.
