The results of experimental studies on registration of the radiative component of the total heat flux by a thermoelectric detector in a reflected shock wave are presented. An increase in the contribution of radiation to the heat flux with an increase in the intensity of the shock wave is estimated. It is shown that the technique can be used in experiments in shock tubes to isolate the radiative component of the total heat flux, and the thermoelectric detector itself can be successfully used to record such parameters. Keywords: shock tube, thermoelectric detector, radiation heat transfer. DOI: 10.61011/TPL.2023.09.56705.19633
