摘要

To understand effects of air groove on working characteristics of a micro Swiss-roll combustor, combustion of premixed CH4/air was conducted in two micro Swiss-roll combustors, one with an air groove and the other without an air groove. The results showed that the air groove can enlarge the flammable limits of the combustors, and make the combustor stably work at a larger excess air coefficient and a smaller methane flow rate. Meanwhile, it increases radial surface temperature gradient on outer wall of the combustor. Additionally, the combustor with an air groove was numerically simulated. The numerical results indicated that high-temperature combustion products has a strong role in heating incoming premixed mixtures. On one hand, it makes premixed flame surface tilt across inlet channel; on the other hand, it changes flame position in a micro-combustor with velocity, excess air coefficient and heat loss to the surroundings.
