Mathematical Simulation of the Admixture Transfer by Turbulent Boundary Layer
RÉSUMÉ
A semiempirical model of a turbulent boundary layer with a nonuniform distribution of liquid or fine-dispersed admixtures of low concentrations over a layer's thickness is suggested. The modifications of the algebraic model of turbulent viscosity, which allow for influence of the complex of phases carried by the flow on the turbulent viscosity to be taken into account, are developed. The general characteristic of these phases is that the gradients of their concentrations are normal to the surface flowed around. A noniterative march method for the simulation of a multiphase boundary layer taking into account the influence of the transferred phases on the parameters of the main flow is developed in the paper. It is demonstrated that the algorithms of parallel computing can be successfully applied within the frames of the suggested method. The execution time on the multiprocessor computer is estimated. Some examples of the numerical simulation of the turbulent flows are considered.
