Equations of the multifluid hydrodynamics

The statistical derivation of hydrodynamic equations of dispersed medium is proposed. It is supposed that the interaction between carrier medium molecules and between dispersed particles is potential, and the molecules-particles interaction may be potential or nonpotential. The dynamics of such a system is described by Liouville (or pseudoliouville) equation. The solution of this equation corresponding to the reduced hydrodynamic description of a system is obtained. Every component of a mixture is described by the own set of hydrodynamic variables. The expressions for transport coefficients and interphase forces are obtained in an explicit form.
