摘要 将CT技术中的ART(代数重建)算法应用于火焰的反演,提出了一种基于发射-透射辐射测量的反演非对称层流自由火焰温度场的新方法。模拟算例表明:即使存在辐射量的测量误差,用ART算法反演非轴对称火焰的温度场亦可得到较为精确的结果。 The ART method used in CT technique are extended to reconstruct the temperature distribution in laminar nonaxisymmetric free flames by the measured data of low timeresolution emission and transmission radiation intensities. The results show that the temperature distribution can be estimated with good accuracy, even with noisy input data. Figs 4 and refs 7.
