Entrainment and Flame Geometry of Fire Plumes

摘要

This study concerns the flame structure and fire plume entrainment of natural gas diffusion flames on 0.10, 0.19 and 0.50 m. diameter burners. The heat release rates ranged from 10 kW to 200 kW. Entrainment measurements spanned heights starting very close to the burner surface to distances about six times the average flame heights. Finally, a theoretical study of a steady, buoyant, diffusion flame indicated the importance of the puffing in the entrainment process.
