Query: To the problem of mathematical and physical modeling of the turbulent
  jets of mutually immiscible liquids like the oil and water   Peculiarities of the turbulent two phase and multiphase flows of the mutually
immiscible liquids and averaged differential equations for their modeling are
considered based on the approach, which was first developed and proposed by
Prof. A.I. Nakorchevski as an alternative to a number of the well known
averaged multiphase dynamics equations. The main difference of the new method
was in an averaging of the Navier Stokes equations by phases and components in
time instead of the widely spread spatial averaging in multiphase mechanics.
What was more, introduction of the so called function indicator of the phases
in a flow allowed recognizing the phases in their movement in a multiphase
mixture, both theoretically and experimentally. For experimental study the
special micro sensor was invented and created, which was successfully applied.
In this paper, the method of Nakorchevski is described in application to some
multiphase tasks, and a discussion is presented as concern to advantages of the
method for study of turbulent two phase flows of water oil immiscible mixture,
as well as many other similar mixtures, where it is important to know the
peculiarities of the phases movement and their mixing in a multiphase flow.
