摘要

This study was a theoretical investigation of simultaneous temperature and heat flux measurement using long-wave infrared thermometry based on the infrared measurement technique. First, the radiant properties of substrate materials in the long-wave infrared range and the radiant property relationships in multiple layers was discussed. Solution procedures for the infrared measurement technique in the long-wave infrared region were developed based on the radiant property relationships of a substrate and the transient heat conduction equation. The infrared measurement technique in the long-wave infrared region was validated by comparing the temperature and heat flux obtained from the analytical solutions for the transient heat conduction problem. In addition, the effects of the radiant and thermophysical properties of substrates on the infrared measurement technique in the long-wave infrared region were investigated. Finally, it was found that the infrared measurement technique in the long-wave infrared region could be applicable to practical experiments of simultaneous temperature and heat flux measurement when a substrate with heat transfer surface has small absorption coefficient and small thermal conductivity.
