화재시가 아닌 어느 용기안에 1400℃ 정도되는 물질이 있다고 가정을 하겠습니다. 그럼 이 물질이 방사하는 복사 에너지가 있을 것이라고 생각됩니다. 그 복사 에너지가 1m 떨어져 있는 곳(예를 들어 다른 물체의 표면)으로 전달된다고 한다면 1m 떨어진 곳의 온도를 알고 싶습니다. 그 온도를 실제적으로 계산할 수 있는 공식이나 참고 문헌 또는 simulation tool이 있는지 궁금합니다.
(3) 질문의 경우 용기안에 들어있는 물질이 일정온도로 유지되고 있다고 하면 그 물질을 둘러싸고 있는 복사열 흡수체의 온도는 점점 상승하여 결국 열평형 상태가 되면 열원과 동일한 1400도에 도달할 것입니다. 아래의 수식은 2에 의해 완전히 둘러쌓인 A1으로부터 열이 방출되어 A2 표면에 전달되는 전열량입니다. 두 물체간의 거리나 저온물체의 면적, Emissivity
