Abstract: Panoramic thermographic visualization of a non-stationary thermal fields on the rectangular shock tube end wall was carried out. Thermal fields evolution of outer (end wall) surface during shock wave reflection is studied. Heat fluxes distribution data were obtained at various times within 4 seconds after reflection. The influence of the boundary layer on heat transfer behind the reflected shock wave is analyzed.

Keywords: reflected shock wave, shock tube, non-stationary heat flux, infrared thermography.
