Heat flux detector for use in measuring convective and radiative heat fluxes, especially in a hostile gaseous environment, comprises a metallic body with a central heat flux detector and radiative flux measurement chamber

摘要

Device (100) for checking combustion gas formation and controlling a thermal reaction comprises a tubular metallic body (1) closed at its ends by a plug (2) with input and output paths (8, 9) and a lower cap (3) within which is a metallic lens (11) of high thermal conductivity, of which one of the faces is in contact with a gaseous flux. An isotropic chamber (5) for measuring the radiative flux is arranged to the inside of the metallic body, while a heat flux detector (20) is fixed in the middle of the isotropic chamber.
