The applicability of two-parameter turbulence models to investigation of the impact of free-stream high-intensity turbulence on the characteristics of near-wall flow and heat- and mass-transfer in the steady-state and unsteady boundary layers under the conditions of blowing and suction through permeable surface sections is analyzed. The calculated results obtained in specifying a constant relative mass flow rate parameter in the cases of blowing and suction through permeable sections are compared with the experimental data. The mechanisms of the interaction of blowing and suction of a gas of homogeneous constitution with the flow on two permeable sections upstream and downstream of these sections in the near-wall zone of turbulent boundary layer are studied on the basis of numerical solutions. The calculated results obtained in specifying a time-dependent flow-rate parameter on two permeable surface sections are given.
