Ignitability of Jet A1 Oxygen Co-axial Diffusion Flames Diluted with Inert Gases

In this study, the ignitability characteristics affected by an oxygen coaxial flow diluted with inert gases (nitrogen and helium) were experimentally investigated using Jet A1 diffusion flame configurations. As molar concentration of supplied to increased, dilution gas decreased, which drastically lowered measured minimum ignition energy. When only was without gas, most easily observed, thereby widening range. With a constant oxygen-inert co-flow rate, suppressibility under helium superior that nitrogen as decreased.
