Instantaneous heat flux flowing into wall surfaces of combustion chambers was used for analysis according to waveforms of instantaneous temperatures measured by thin film thermocouples. Such analyses, however, were in fact done using known fixed values of the thermophysical properties. In this study, the instantaneous heat flux has been studied by means of numerical analysis using differential equations (which had an added heat storage term) taking account of the temperature dependency of the thermophysical properties. In addition, related measured values in the previous paper have also been studied again. As a result, it has been concluded that the temperature dependency of the thermophysical properties should be considered when analyzing instantaneous heat flux.
