Abstract
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.
期刊介绍:
Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
