Two-phase flow is a mass system. Kinetic approach to such systems makes it necessary to take into account interactions of particles of various sizes in a flow and their interactions with the channel walls. Having overcome mathematical complications, a model of particles interactions with the channel walls was developed. The solution of this model leads to relations obtained earlier by various authors in a purely empirical way. A definition of a statistical system of particles in a flow it given and substantiated. Mathematical equations describing a statistical system of particles are derived. The solution of these equations made it possible to substantiate main parameters characterizing flow regimes under study.
