Calculation of Swirled Nonisothermic Layer Flow of Two-Phase Non-Newtonian Medium on a Conical Surface

Abstract

We consider the non-isothermic layer flow of two-phase non-Newtonian medium on the inner surface of the conical tube. The flow regime is laminar , axisymmetric and steady. The rheological state of the medium is described by the generalized law Ostwald de Ville. We also took into account the dependence of the temperature of medium consistency. The conservation equations of mass, momentum and energy mechanics of heterogeneous medium is used in quasi-homogeneous approximation. The recorded in biconical coordinate system equations are solved by method of equal costs surfaces. The provisions of equal costs surfaces are determined from the condition of the flow of the medium constancy between them. Conservation equations, written on the flow lines, are simplified and take the form of ordinary differential equations on the longitudinal coordinate. So that to calculate the partial derivatives on the transverse coordinate, which are present in the right part of the differential equations, the grid solutions are presented in the form of series expansion. The system of constructed ordinary differential equations is solved numerically.
