A turbomachine combustor includes a combustor cap having a cap surface and a wall that define, at least in part, a resonator volume. A plurality of injection nozzle members extend from the cap surface. Each of the plurality of injection nozzle members include an inner nozzle member and a plurality of outer nozzle members. An adjustable conduit extends through the wall into the resonator volume. The adjustable conduit includes an internal passage having a dimensional parameter. A combustor dynamics mitigation system is operably connected to the combustor cap. The combustor dynamics mitigation system includes a controller configured and disposed to control one a size of the resonator volume and the dimensional parameter of the adjustable conduit to modify combustor dynamics in the combustor.

A turbomachine combustor includes a combustor cap having a cap surface and a wall that extends about the cap surface to define a cap volume, and a plurality of nozzle members that extend from the cap surface. The plurality of nozzle members include a center nozzle member and one ore more outer nozzle members. A combustor dynamics mitigation system is arranged in the combustor cap and includes plurality of divider members that extend from the wall toward the center nozzle member. The plurality of divider members define a plurality of parallel resonator volumes. The combustor dynamics mitigation system also includes a plurality of tubes that extend into corresponding ones of the plurality of parallel resonator volumes.

A nozzle includes a center body that defines an axial centerline and a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud. A plurality of vanes between the center body and the shroud comprise a radially outward portion separated from the shroud. A method for enhancing flow through a nozzle includes flowing a fuel through a center body and flowing a fluid stream across a vane located between the center body and a shroud surrounding at least a portion of the center body. The method further includes flowing the fluid stream between a radially outward portion of the vane and the shroud, wherein the radially outward portion of the vane is separated from the shroud.
