Abstract

Studies on the ignition and flame anchoring of a coaxial gaseous methane-oxygen jet have been performed. The experiment has been set up to record by high-speed visualization techniques the start-up and ignition transients. Results from image processing and data recording are evaluated for correlation of injection and stationary combustion conditions. The capability to perform reliable ignition of a gaseous methane/oxygen jet has been highlighted. Several phases of ignition (“expanding” and “stabilizing”) have been found with specific phenomenology, depending mainly on the ignition time. The influence of the mass flow rate and momentum flux ratio on ignition process is also discussed. Finally the flame stabilization (anchoring or detached flame) is investigated, showing important dependency with the jet injection characteristics, especially the propellants velocity ratio.
