Abstract: A swirler, such as for swirling air in a fuel injector of a gas turbine engine, includes a swirler body with opposed inlet and outlet ends with a swirler wall extending therebetween along a longitudinal axis. The inlet end of the swirler body defines an inlet opening. A plurality of swirl slots is defined through a portion of the swirler wall that converges toward the longitudinal axis in a direction from the inlet opening toward the outlet end of the swirler body. The swirl slots are radially off-set with respect to the longitudinal axis for imparting swirl on a flow passing from the inlet opening, through the swirl slots, and past the outlet end of the swirler body.

Abstract translation: 旋流器，例如用于燃气涡轮发动机的燃料喷射器中的旋转空气，包括具有相对的入口端和出口端的旋流器主体，其中沿着纵向轴线在其间延伸有旋流器壁。 旋流器主体的入口端限定入口开口。 多个涡流槽通过旋流器壁的一部分限定，该部分沿着从旋流器主体的入口开口朝向出口端的方向朝着纵向轴线会聚。 漩涡槽相对于纵向轴线径向偏移，以在从入口开口，通过涡流槽并经过旋流器主体的出口端的流动上产生涡流。
