摘要
It has been established experimentally that in helium injection through a permeable wall into an air flow of the same temperature the heating of the wall up to about 8°C is observed. On the other hand, in the outer part of the boundary layer the flow is cooled. Such a structure of the thermal boundary layer is caused by redistribution of heat in the boundary layer due to the diffusion thermoeffect (Dufour effect). The magnitude of the thermal effect on the wall is preserved in transition from a laminar to a turbulent mode of flow.
