Abstract

Plate thermometers are used for measuring the radiative heat flux in high-temperature surroundings. The heat flux is calculated from the temperature measured at the back surface of the stainless steel surface of the meter. Heat fluxes from a Schmidt-Boelter gauge are measured as reference heat fluxes. A combined conductive coefficient is introduced to consider the heat loss to insulation, conduction through the stainless plate depth, and conduction from the non-uniform temperature of the plate of the plate thermometer. This coefficient is obtained using the repulsive particle swarm optimization.

고온환경의 복사열유속을 측정하기 위하여 판열유속계를 제작하였다. 열유속은 스테인리스스틸로 제작된 판열속계 뒷면에서 측정된 온도를 이용하여 계산되어진다. 스미트-볼터계로 측정된 열유속을 기준값으로 이용하였다. 단열재로의 열손실, 판열유속계 두께방향으로의 전도 및 평판의 위치에 따라 온도가 상이하여 발생하는 열전달 등을 고려하기 위하여 전도상수를 도입하였다. 이 상수는 반발입자군집 최적화법으로 구하였다.
