Abstract: Experimental and numerical simulation studies were conducted on the zoned combustion characteristics of a multi-nozzle array combustor, so as to uncover the stabilization mechanism of combustion zoning and the flame morphology in such combustors. Through experimental investigations, flame morphologies under varying equivalence ratios and nozzle bulk velocities were obtained, while numerical simulations were employed to acquire the non-reacting and reacting flow characteristics of the combustor. Results reveal that, under non-reacting conditions, a large central recirculation zone is formed. Reacting flow field and experimental results show that interactions among the multiple nozzles lead to the formation of small-scale recirculation zones, which promote the entrainment of flue gas in the pilot zone and enhance overall combustion stability. As the nozzle bulk velocity increases, the extent of the recirculation zone remains relatively stable, enabling the combustor to maintain stable combustion over a wide velocity range. With an increase in the equivalence ratio, the flame intensity in the central pilot zone gradually intensifies, and the surrounding main combustion zone is progressively ignited. Transient OH^* chemiluminescence images demonstrate stable combustion morphologies at different periods. Relevant research results may serve as references for the design of zoned multi-nozzle array combustors.
