Abstracts:

Non-isothermal flow of two-phase media with complex rheological equation of state in areas with permeable surfaces are present in many industrial processes. In connection with this work is to construct a mathematical model of non-isothermal laminar flow of non-Newtonian two-phase media with their filtering through the permeable surface of the workers and the numerical scheme for calculating them. Equations of mechanics of multiphase media stored in an arbitrary orthogonal coordinate system associated with the flow region. To solve this problem a method adapted surfaces of equal costs. We consider two-dimensional and axisymmetric fl ows and carried out specific numerical calculations of thin-layer flow on a flat and rotating surfaces and a flat channels and axisymmetric tubes for fluids with rheological equation of state Ostwald de Waele. The effect of the filtering process on the hydrodynamic and non-isothermal conditions in the flow domain. The results obtained are of great practical interest for various technological applications: the processes of mixing and dispersion, separation and condensation of two-phase media in the filter apparatus, the implementation of intensive heat transfer boundary layer control, etc.
