An experimental work was made to investigate the thermal and heat transfer behaviors of a multi-fuel-jet inverse diffusion flame (IDF) with induced swirl. Flame appearances, temperature fields and wall static pressures were compared between the swirling and non-swirling IDFs under identical air/fuel flow rates. Results show that either flame consists of a lower flame base and an upper flame torch where main combustion takes place. However, the main reaction zone in the swirling IDF and is closer to the burner exit and the flame length is much shorter than the non-swirling IDF. Both the radial wall static pressure profile and radial heat flux distribution of the swirling IDF are M-shaped at low nozzle-to-plate distances, and both are influenced by the swirl effect.
