【摘要】 本文利用低密度激波管和辐射计,在不同的温度和密度状态下,就杂质辐射在分谱和累积辐射条件下对高温空气平衡辐射的影响进行的实验研究;给出了在不同条件下的实验结果,并做了简单分析。实验结果表明:少量杂质对高温空气平衡辐射的影响较大,这为计算尾流辐射场时,考虑杂质辐射的影响提供了实验依据。更多还原

【Abstract】 This report presents the experimental researcg at different tempera-ture and densities about the influence of impurity on radiation at spectral and integral radiation on air equilibrium radiation by using the radiometer in the low density shock tube. The experimental results were given at different conditions and simple analysis was made. The experimental results show that the influence of a small amount of the impurity on air equilibrium radiation is rather big; When wake radiation field is computed, the influence of impurity on radiation must be considered.更多还原
