| 本文对漫灰均温物体在常物性条件下对外辐射传热的Ｙｏｎｇ值计算建立了数学模型。通过与物体内能Ｙｏｎｇ公式的数值计算比较，得出了辐射能量的Ｙｏｎｇ值不大于内能Ｙｏｎｇ值的结论。从初步的热射Ｙｏｎｇ值计算公式发现。Ｙｏｎｇ与物体表面辐射率有关。 |
| 英文摘要: |
| This paper established a mathematical model for calculating the exergy of radiation heat transfer of gray bodies with homogeneous temperature and constant physical properties. Using this model, analysis and calculations were carried out and the results were compared with those obtained from the internal-energy exergy equation of gray bodies. It was concluded from the comparison that the exergy of radiative energy is not greater than the exergy of internal energy. From the derived equation of radiation exergy, the exergy depends on the emissivity of body surface. |
