    • A system for dampening combustor dynamics within a turbomachine. The system may include at least one resonator installed adjacent a head-end region of a combustion can. The at least one resonator may include a first side having a plurality of holes forming a cold side hole pattern; a second side having a plurality of holes forming a hot side hole pattern; and a cavity substantially defined by the first side and the hot side. The cold side hole pattern may be oriented such that each of the plurality of holes in the cold side hole pattern allows for a jet of a cooling air to substantially impinge a second side facing surface; and wherein the hot side hole pattern is oriented such that each of the plurality of holes in the hot side hole pattern allows for a jet of a working fluid to substantially impinges a first side facing surface.
    • 一种用于抑制涡轮机内燃烧室动力学的系统。 该系统可以包括邻近燃烧罐的前端区域安装的至少一个谐振器。 所述至少一个谐振器可以包括具有形成冷侧孔图案的多个孔的第一侧面; 具有形成热侧孔图案的多个孔的第二侧; 以及基本上由第一侧和热侧限定的空腔。 冷侧孔图案可以被定向成使得冷侧孔图案中的多个孔中的每一个允许冷却空气的射流基本上撞击第二侧面; 并且其中所述热侧孔图案被定向成使得所述热侧孔图案中的所述多个孔中的每一个允许工作流体的射流基本上撞击第一面对面。
