Principles of heat flux measurement by circular foil heat flux sensors, also known as Gardon gages, are analyzed when the gages are subjected to a mixed convective/radiative heat flux. The specific objective of this work is to present the analysis and a methodology for estimating the error in the measurement of mixed convective-radiative heat flux, which is the difference between the true surface-sensed heat flux and the flux determined from the gage output using a calibration based on purely radiative heat flux.
