ABSTRACT
Aggregative unstable disperse systems are characterized by the inconsistency of the state of the medium, caused by a continuous change in the physical properties of the particles, that is, change in the volume and size of particles as a result of their interaction, collision and coalescence. The essence of the processes of coalescence and breaking of droplets and bubbles consists in the loss of aggregative and, in some cases, sedimentation stability of the dispersed system as a whole, under the influence of external forces or spontaneously because of the desire to reduce excess surface energy. The minimum particle size characterizes such a state of the disperse system, which is more prone to coalescence, and the maximum dimensions characterize the state of the system more prone to deformation and breaking of droplets and bubbles. The deformation of drops and bubbles is characterized by a violation of the balance of external and surface forces acting on a particle in a turbulent flow.
