Abstract: An inline fluid damper device comprises a flow-through conduit configured to be placed inside a larger exterior conduit through which a fluid flows. The flow-through conduit is elongated and extending around a center axis. The damper device also comprising an indirect flow conduit coupled with the flow-through conduit. The indirect flow conduit is also configured to be placed inside the larger exterior conduit. The flow-through conduit and the indirect flow conduit are configured to dampen one or more flow fluctuations or pressure fluctuations in the fluid flowing in the larger exterior conduit by dividing the fluid into a first portion that flows along the center axis through the flow-through conduit and a second portion that concurrently flows outside of the flow-through conduit along the center axis and along a different direction.

Abstract: A mixer assembly for a gas turbine engine. The mixer assembly includes a housing and a fuel injection port. The housing has a passage formed therein, and the housing includes a passage wall facing the passage. The fuel injection port is fluidly connected to a fuel source and is configured to inject a hydrocarbon fuel into the passage. At least a portion of the passage wall is a coated passage wall. The coated passage wall is (i) coated with a layer of a catalytic metal and (ii) located downstream of the fuel injection port.
