A heat exchanger including a fluid circuit in which an incoming fluid stream is progressively divided into multiple smaller streams, each of which delivers the heat exchange fluid into one or more heat exchange sections of the device; and/or in which multiple fluid streams of the fluid circuit are discharged from one or more heat exchanger sections, each of which are progressively combined into one or more larger streams before exiting the device. The heat exchanger may have a thin body portion and a thick body portion and may adapt a depth of the fluid circuit to the changes in thickness of the heat exchanger body. The heat exchanger may form a structural component and may integrate multiple materials to provide both heat exchange and structural functionality into a single device. Other structural fluid transfer devices having fluid flow and structural functionality also are provided.

Heat exchanger with progressive divided flow circuit, structural load bearing design

Provided is a flexible hose assembly having a flexible tube for conveying fuel through a first fuel passage formed interiorly of the flexible tube and a flexible hose surrounding the flexible tube and forming therewith a second fuel passage. The flexible tube provides internal support for the flexible hose while also allowing for flow of fuel through the second fuel passage and the fuel passages are separate from one another along a length of the flexible hose assembly. When one of the fuel passages is in a low flow or no flow condition, fuel flowing through the other of the fuel passages acts to cool the fuel passage in the low flow or no flow condition to prevent stagnant fuel in the passage from heating up and coking.

Flexible hose assembly with multiple flow passages

Provided is an injector () having a plurality of injector modules () that include a spray cup having a chamber and a plurality of radial air passages for directing air radially into the chamber, and a pressure swirl atomizer attached to the spray cup and having a fluid passage for directing fluid axially into chamber and an air passage for directing air axially into the chamber. By providing radial and axial air flow and axial fuel flow into the chamber, the fuel may be mixed to prevent local hot spots that lead to high NOx emissions, and a stable flame may be maintained without autoignition and flashback. The axial air flow also prevents recirculation zones from forming at a base of the spray cup, provides improved atomization and enhanced combustion.

Direct injection multipoint nozzle

A fuel nozzle of a variety for dispensing an atomized fluid spray into the combustion chamber of a gas turbine engine. The nozzle includes a first fluid conduit extending along a longitudinal central axis from an upstream end to a downstream end portion terminating to define a primary discharge orifice, a second fluid conduit which is received coaxially over the first fluid conduit as extending along the central axis from an upstream end to a downstream end portion terminating to define a secondary discharge orifice disposed generally concentrically with said primary discharge orifice, and a third fluid conduit which is received coaxially over the second fluid conduit as extending along the central axis from an upstream first end to a downstream second end. The outer surface of the downstream end portion of the first fluid conduit and the inner surface of the downstream end portion of the third fluid conduit define therebetween a generally annular, internal mixing chamber. First and second fluid inlet ports are provided as extending along longitudinal first and second port axes in fluid communication with, respectively, the second and third fluid conduits and the mixing chamber. The second inlet port is disposed angularly to the first inlet port such that the second port axis intersects the first port axis within the mixing chamber to define an impingement locus for the admixing of a first fluid from the second fluid conduit and a second fluid from the third fluid conduit.
