Title of the articleMathematical model of the unsteady flow of non-compressible gas with heat transfer in the axle symmetric canals of technological equipment
Abstract.Research in the work based on the numerical solution the unsteady equations on the boundary layer. As trailing ties, necessary for the solution of primary system equations involved expressions for the laws of friction and heat transfer, sensitive to the studied variety’s indignant at the affects. Deduction the indicated expressions be built on utilization method the relative conformation, the two layer model the dynamics and heat turbulent boundary layers, the hypothesis Prandtl and Furie, and the specific forms of approximation of the radial distributions of the turbulent tangent tensions of friction and the densities of heat streams in different phases of unsteady process. As the result of the accomplishable mathematical experiment defined the particular qualities of the behavior of dynamic and heat turbulent boundary layers in the conditions of changed temperature pressure or expenditure of the work body.
Keywords.Unsteady, non-isothermal, mathematical model, gaseous flow, axle symmetry canal.
