Abstract
The dynamic and thermal characteristics of unsteady near-wall flows are investigated numerically on the basis of two-parameter turbulence models under conditions of high-turbulence free stream and impact of perturbing heat- and mass-transfer factors in the boundary layer. The effect of mass-transfer parameters considered on the permeable section on the development of dynamic and thermal processes in the steady-state turbulent boundary layer is studied and the boundary layer structure along the surface is investigated. The mutual action of time harmonic oscillations of the velocity of outer inviscid free stream and the heat-transfer parameters on wall on the development of time-dependent heat-transfer characteristics in turbulent flow is analyzed. The numerical results are compared with experimental and theoretical data.
