Title of the articleOn the limits of the application of a mathematical model of unsteady compressible gas flow in axisymmetric channels
Abstract.A mathematical modeling of the physical phenomena is very perspective direction of scientific researches. However not always one or another mathematical model describes the physical phenomenon adequately. Reasons are different. The use of mathematical models for description of the physical phenomena is limited to the scopes of the accepted assumptions, that in the total is described by the borders of application of the examined mathematical model. The presented mathematical model of turbulent frontier layer, for that the borders of application are certain, describes the unsteady-state non-isothermal flow of incompressible gas in axle symmetric channels with a heat exchange. Research is built on the basis of numeral decision of non-stationary equalizations of frontier layer with the use of closing correlations for the coefficients of friction and heat emission at corresponding regional.
Keywords.restrictions, unsteady-state, non-isothermal, mathematical model, gaseous flow, axle symmetric canal.
