In this paper we consider the processes of dynamic interaction between the boiling particles of the dispersed phase of the emulsion leading to the large droplet breakup.
It indicates the differences in the consideration of forces that determine the breaking of nonboiling and boiling droplets. It is determined by the possibility of using the model to define the processes of displacement, deformation or fragmentation of the inclusion of the dispersed phase under
the influence of a set of neighboring particles.
The paper also studies the dynamics of bubbles in a compressible liquid with consideration for interfacial heat and mass transfer. The effect of standard and system parameters on the intensity of cavitation processes is considered. Physical transformations during cavitation treatment of liquid are caused not only by shock waves and radiated pressure pulses, but also by extreme thermal effects. At the stage of ultimate bubble compression, vapor inside the bubble and the liquid in its vicinity transform into the supercritical fluid state . The model analyses microflow features in the inter-bubble space and quantitatively calculates local values of the velocity and pressure fields, as well as dynamic effects.
