One-velocity model of heterogeneous media

One-dimensional non-stationary flows, and also flat (axisymmetrical) stationary flows of an onevelocity multicomponent mixture are investigated. It is shown, that for considered flows the secular equation has the multiple radicals. The singularities of a realization of a characteristics method for one-velocity model of dispersible environment are circumscribed. The problem about stability of the solutions in relation to small disturbances is considered. For series of particular mixtures the correctness of a Cauchy problem is shown.
