赤外線サーモグラフィーによる常温域の対流伝熱計測とその定量評価に関する研究

The infrared thermography near ambient conditions is proposed to estimate convective heat transfer quantitatively. The correlation between a radiation temperature and a true temperature is calibrated at first. The surface temperature distribution is then measured for laminar natural convection along a vertical flat plate as one of applications. We further estimate natural cooling fin using the present infrared thermography to confirm the applicability. The measurement error is also estimated using ANSI/ASME PTC 19.1-1985 measurement uncertainty to confirm the accuracy. It is revealed from a series of application experiments and error analyses that the proposed technique of measuring temperature is useful to estimate convective heat transfer quantitatively.
