摘要：

This article presents a simulation investigation for simultaneous determination of distributions of temperature and soot volume fraction in a nonoptically thin sooting flame using a decoupled reconstruction method. Flame temperature and emissivity images can be calculated from two monochromatic radiative intensity images in the visible spectrum range. Then, the distributions of temperature and soot volume fraction were reconstructed from flame temperature and emissivity images. Based on experimental data from a laminar ethylene diffusion flame available in the literature, the effects of measurement errors, detection wavelengths, and optical thickness on the accuracy of the reconstruction have been investigated.
