Abstract

Optical investigations of hybrid combustion flame are essential to better understand their combustion mechanism. Therefore, combustion tests using paraffin-based fuels and gaseous oxygen (GOX) were performed in the framework of this research. The combustion flame was analyzed with two decomposition methods, which give a low-dimensional representation of the complex flow structures and identify the main combustion phenomena. To prove the reliability of this analysis, a modes reconstruction has been performed. The results show that the output of the reconstruction provides a good representation of the original combustion video frames. This means that the low-dimensional modes representation is able to efficiently and correctly describe the main combustion phenomena in the combustion chamber.
