Experimental and simulation investigation of 3-D soot temperature and volume fraction fields of afterburner flame

Abstract

The temperature and soot volume fraction in afterburn flame are very important parameters in flame analysis and burner design. A novel method that combines the 3-D emission measurement technique and the camera position and attitude calibration by using the translation and rotation matrix is proposed. The spectral intensities of oxygen-enriched combustion and afterburner flame facility were designed for testing purposes. The theoretical analysis and experimental results are provided in this paper. The results demonstrated that this novel technique can provide good measurement accuracy with high spatial resolution.
