Interaction of radiation with turbulent fluctuations in a boundary layer
Abstract
The influence of radiation on turbulent heat and momentum transfer is examined by applying the notion of 'equilibrium' turbulence structure in the main part of the boundary layer and using simplified equations for the temperature fluctuation intensity in this zone. The turbulent motion of a gas at sufficiently low velocities, so that compressibility effects can be neglected, is considered; the physical properties of the medium are assumed to be constant; and it is also assumed that the gas flows over a plane surface and absorbs a certain external monochromatic radiation intensity at the boundary. Among other results, it is shown that if the absorption coefficient is independent of the temperature, the intensity of the temperature fluctuations in the thickness of the thermal sublayer does not depend on the radiant flux.
