摘要

This paper presents the author's method for the heat flux evaluation on the basis of a thermal photograph. This method is based on the comparison of surface temperatures of two areas where one of them is a thermally loaded with a known heat flux and the other control area which is not thermally loaded. With the method presented in the article analysing heat fluxes in places of high heat flux gradients occurring within heat leakage bridges, especially the service ones connected with the material humidity where heat flux density sensors can give substantial errors when the flux on the sensor surface is averaged.
