摘要

基于Monte-Carlo法建立了圆筒形黑体空腔模型

对黑体空腔模型的有效发射率进行计算

分析了不同腔体几何结构、腔体材料发射率、探测器距腔口距离等因素对黑体腔有效发射率的影响

并与有限元分析法所得结果进行对比。结果表明:由Monte-Carlo法得到的结果与有限元分析法基本符合

即长径比较大、孔径比较小、腔体材料发射率较大时

黑体腔有效发射率较大。

Abstract

Based on the Monte-Carlo method

cylindrical blackbody cavity model is established

effective emissivity of blackbody cavity model is calculated

analyze impact of different cavity geometry structure

emissivity of cavity materials

distance from detector and other factors on black body cavity effective emissivity

and compare with the results obtained by finite element analysis method. The results show that the results obtained by MonteCarlo method are in accord with that by finite element analysis method

namely the longer diameter is larger

the aperture ratio is smaller

the cavity material emissivity is larger

while blackbody cavity has larger effective emissivity.
