Sinopsis

The paper presents a semi-empirical mathematical model of turbulent transport in the boundary layer, constructed by generalizing the experimental data on the reaction of the turbulent boundary layer to intensive control influences. The results of its use in numerical modeling and investigation of heat transfer and friction in some practical applications, such as the creation of a gas curtain in flowing in nozzles, the imposition of pressure pulsations on the flow, as well as flow past surfaces with damping cavities are presented. The results received testify to an opportunity of active control of transfer processes intensity in a boundary layer by purposeful influence on near-the-wall turbulence.
