Effect of Secondary Flow Area on Diffusion Flame Stability

The focus of this research was to understand the effects of varying the secondary flow area in a single coaxial injector on flame stability in an experimental non-premixed flame burner. Gaseous methane and gaseous oxygen were utilized as reactants with the oxidizer being the primary flow and the fuel being the secondary (annular) flow. The reactants were ignited in an optically-accessible combustion chamber with a retractable spark plug, and the product flame behavior and flame standoff distance were observed. Results on flame stability based upon equivalence ratio and primary reactant Reynolds number are presented.​
