摘要

Experiments are conducted to investigate the effect of a proposed combustion technique, namely annular counterflow, on jet diffusion flame blowout limit extension. Annular coun-terflow is formed in a concentric annulus, in which a fuel jet is ejected from a nozzle and air is sucked into an outer cylinder encompassing the nozzle. Normal video filming, schlieren technique and image processing devices are employed to record and visualize sundry flame morphologies triggered by this technique. Results show that the preponderant factor governing such an extension is the air-suction momentum flux.
