Abstract: A heat transfer arrangement includes two or more heat transfer cells. The heat transfer cells together define a boundary between a higher temperature region and a lower temperature region. Each of the two or more heat transfer cells includes two or more walls defining a fluid tight cavity. One or more wick is fused to an inner surface of one or more of the walls to wick liquid from a lower temperature portion of the cavity to a higher temperature portion of the cavity. Combustors having heat transfer arrangements with heat transfer cells and methods of making heat transfer arrangements are also described.

Abstract: A strainer body strainer body has a conical or bullet-like shape and includes a tip portion, a midsection, and a base portion. The midsection connects the tip portion to the base portion such that the tip portion, midsection, and base portion are aligned with one another along a straining axis defined by the strainer body. The strainer body includes a plurality of layers fused to one another and angled relative to the straining axis. The plurality of layers define flow passages that extend through the strainer body to impound particulate entrained in fluid traversing the strainer body through the flow passages of the strainer body.

Abstract: A nozzle includes a nozzle body defining a longitudinal axis. The nozzle body includes an inner air passage fed by a radial swirler and having a converging conical cross-section. A first fuel circuit is radially outboard from the air passage with respect to the longitudinal axis. A second fuel circuit is radially outboard from the first fuel circuit with respect to the longitudinal axis, wherein each of the first fuel circuit and the second fuel circuit extends from a respective fuel circuit inlet to a respective annular fuel circuit outlet. An outer air passage is defined between a fuel circuit outer wall and an outer air passage wall, wherein the outer air passage is a converging non-swirling outer air passage.

Abstract: A nozzle includes a nozzle body with an inner air passage fed by a first radial swirler and a second radial swirler axially downstream of the first radial swirler. A first fuel circuit is axially between the first and second radial swirlers. A second fuel circuit is axially downstream of the second radial swirler, wherein each of the first fuel circuit and the second fuel circuit extends from a respective fuel circuit inlet to a respective annular fuel circuit outlet. An outer air passage is defined between a fuel circuit outer wall of the second fuel circuit and an outer air passage wall, wherein the outer air passage is a converging non-swirling air passage. An intermediate air passage can be defined between an intermediate wall and the second radial swirler, wherein the intermediate air passage is a converging non-swirling air passage.

Abstract: A system for inspecting spray nozzles includes a nozzle operatively connected to a source of pressurized liquid for issuing a spray from the nozzle. The system also includes a sensor positioned to detect frequencies of resonant modes in the spray. The nozzle and sensor can each be mounted to a spray test booth. A method of inspecting a spray nozzle includes issuing a liquid from a spray nozzle as a spray and using a sensor to detect frequencies of resonant modes in the spray. The sensor can include a diaphragm and detecting frequencies can include impinging at least some of the spray on the diaphragm, and monitoring vibrations of the diaphragm.

Abstract: An injector includes a fuel distributor with a first fluid inlet and a first fluid outlet, with a first fluid circuit for fluid communication between the first fluid inlet and the first fluid outlet. The fuel distributor includes a second fluid inlet and a second fluid outlet, with a second fluid circuit for fluid communication between the second fluid inlet and outlet. The fuel distributor defines a spray axis. The first and second fluid outlets can be radially adjacent and/or can be substantially aligned axially relative to the spray axis, e.g., for issuing multiple different fuels from substantially the same outlet.

Abstract: A flow directing apparatus for directing fluid flowing therethrough includes a flow body defining an upstream facing inlet surface and an opposed downstream facing outlet surface with a bore defined through the flow body. The bore includes an inlet portion of the bore extending in a downstream direction from an inlet where the bore meets the inlet surface. An intermediate portion of the bore extends in a downstream direction from the inlet portion of the bore. A backstep portion of the bore extends downstream from the intermediate portion of the bore to an outlet where the bore meets the outlet surface. The intermediate portion of the bore has a cross-sectional flow area that is smaller than that of the inlet portion and smaller than that of the backstep portion to provide a backward facing step in flow area for flow through the bore.
