Abstract: A combustor assembly (12) includes a convergent segment (34) followed by a divergent segment (36) to advantageously improve combustion. The combustor assembly includes a first segment (34) beginning at a forward end (24) that transitions to a second segment (36) past a transition segment (58) in a direction along a combustor axis (22) toward an aft end (26). The reduction in cross-sectional area within the first segment (34) provides desirable fuel and air mixing properties. The convergent first segment (34) in combination with the divergent second segment (36) decreases residence time of fuel-air mixture within the combustor chamber that decreases production of undesirable emissions from the combustor assembly.

Abstract translation: 一个燃烧器组件（12）包括一个收敛段（34），后面跟着一个扩张段（36），以有利地改善燃烧。 燃烧器组件包括在前端（24）开始的第一部分（34），该第一部分在沿着燃烧器轴线（22）的方向上朝向后端（26）过渡到经过过渡部分（58）的第二部分（36） ）。 第一段（34）内的横截面积的减小提供了期望的燃料和空气混合特性。 会聚的第一部分（34）与发散的第二部分（36）结合减少了燃烧室内燃料 - 空气混合物的停留时间，这减少了来自燃烧室组件的不希望的排放物的产生。
