Ratio pyrometry is commonly used for high temperature measurements. It is particularly useful for measuring the temperature of soot in flames, because measurements are nonintrusive and can be performed with a standard commercial DSLR camera. However, radiation reabsorption by soot particles can lead to significant error in flames with high soot concentrations. A correction must be implemented to account for this. One approach to this correction for two-color ratio pyrometry measurements is compiled and documented by Kempena and Long [1]. The goal of this study is to create a Matlab code that implements the radiation reabsorption correction as described. The MATLAB code will be used to examine the effect of soot radiation reabsorption in coflow diffusion flames experiments conducted in the Laboratory for Advanced Combustion and ENergy Research (LACER) at Washington University in St. Louis.
