This study explored the relationship between the RGB color space and the temperature of hydrogen flames with thermal reflection principles. The prediction model based on CCD and infrared (IR) image were compared. The model based on RGB difference as inputs for CCD image showed an average relative error of 9.8314%. The model based on infrared image RGB values showed an average relative error of 6.6652%.

“…Arana et al [21] adopted the full-field light extinction method to measure soot volume fraction distributions in partially premixed laminar co-flow ethylene flames. Zheng et al [22] proposed a multiwavelength radiation thermometry method employing multispectral imaging technology to measure flame temperature and emissivity. Joo et al [13] used a CCD camera to obtain the radiation intensity of the methane-air laminar flame boundary.…”

This work proposed a novel model to simultaneously reconstruct temperature distribution and soot volume fraction field for two-dimensional thin-slice flames using the knowledge of monochromatic radiation intensities at two wavelengths using a CCD camera. The deduction process and numerical analysis of the model were described. Effects of wavelength combinations and measurement errors on reconstruction accuracy were considered in detail. Numerical results have proven the model’s accuracy and showed that the temperature and soot volume fraction fields can be reconstructed well even with noisy input data from flame radiation. In addition, a series of experiments were conducted on a mesoscale combustor to obtain the real thin-slice flames for further experimental reconstruction via the model. The experimental results indicated that the proposed model can successfully reconstruct the flame temperature distribution and soot volume fraction field and the main features of thin-slice flames also can be reasonably reproduced.
