| Semiempirical model of turbulent boundary layer with nonuniform distribution of little concentrations of an injected liquid or fine-disperse phase additives on the thickness has been elaborated. The modifications of algebraic model of turbulent viscosity are carried out. They have allowed to take into account the joint action of a complex of phases, which move under the influence of basic flow and modify flow characteristics. The general phenomena of these phases is normal to streamlined surfase gradient of their concentration. The without-iterational marching method of multiphase boundary layer has been carried out. The phenomena of elaborated method is an account of the moving phases influence on the basic flow parameters. The possibility and effectiveness of application in the frames of given method of a parallel processing algorithms is shown. The time of computations with the account of multiprocessor's computer architecture has been estimated. The examples of predictions of flow characteristics are presented. |
