Аннотация

This paper is devoted to the results of an experimental study of heat transfer in the boundary layer of a flat plate with the impact of weak shock waves on the leading edge. The experimental study was conducted on the model of blunt flat plate at Mach 2. To generate weak shock waves into the flow, a roughness on the lower part of the nozzle of the test section of wind tunnel was used. Visualization experiments of heat flows were carried out using an infrared camera. As a result of experiments, data on the features of heat transfer on the surface of a flat plate were obtained. A double longitudinal structure in the form of a temperature change defect caused by the interaction of two vortices with the model surface is shown. Temperature changes in the vortex region downstream in a direction parallel to the leading edge have a similar structure, but different amplitudes.
