Case study for swirling flow and porous media on triple coaxial ports inverse diffusion flame

In this study, the effects of swirling flow and porous media of triple coaxial ports inverse diffusion flame (TCP-IDF) on the flame shape, temperature and gas emissions are studied. In addition, a comparison between swirling and non-swirling TCP-IDF burner conducted using 5° air swirler. On the othe...
