FEATURES OF THE SURFACE HEATING OF A HEAT-INSULATED BLUNT PLATE IN THE STRONG-INTERACTION REGIME

Results of an experimental investigation of the heating of the surface of a blunt plate, made of a material having a low heat conductivity, in a wind tunnel in the regime of strong viscous-nonviscous interaction of the boundary layer on the surface of the plate with the incident fl uid fl ow are presented. It is shown that the installation of a wedge on this plate in the vicinity of its trailing edge changes the disturbed fl ow region and the temperature distribution over the surface of the plate upstream of the wedge as far as the leading edge of the plate.
