Аннотация: This paper explores the possibility of non-invasive heat fluxes visualization and analysis of high speed channel flows using infrared thermographic registration. Panoramic IR imaging was performed as the plane shock wave have passed through the test chamber and diffracted on a rectangular obstacle (6 × 2 × 48 mm) on the wall in the shock tube channel (24 × 48 mm). The evolution of the heat fluxes maps on the test chamber inner walls (IR-transparent windows) are recorded using a high-speed infrared recorder with operating range 1.5 − 5.1 µm. The images of thermal fields were compared with shadow imaging and two-dimensional numerical simulation of the non-stationary gas-dynamics flow around after the shock wave diffraction on the ledge.
