Systems and methods for dampening combustor dynamics in a micromixer

摘要

Embodiments of the present application can provide systems and methods for dampening combustor dynamics. According to one embodiment, the system may include a micromixer. The system may also include at least one annular resonator (122) disposed within the micromixer adjacent to a cap face plate or an impingement plate of the micromixer. The at least one annular resonator (122) may include a first side (124) including a number of holes forming a cold side hole pattern, a second side (128) including a number of holes forming a hot side hole pattern, and a cavity (126) substantially defined by the first side (124) and the second side (128).
