Abstract

A flow device for a combustor assembly defining a longitudinal axis around which the flow device is positioned is provided. The flow device includes a body extended around the longitudinal axis. The body includes a first wall and a second wall separated longitudinally from one another along the longitudinal axis. A fuel injector passage is defined through the body coaxial to the longitudinal axis. A plurality of vane walls is extended radially between the first wall and the second wall relative to the longitudinal axis. A radial flow passage is extended between the plurality of vane walls and the fuel injector passage.

First claim

What is claimed is:

1. A flow device for a combustor assembly, the flow device comprising:
a body extended around a longitudinal axis, wherein the body comprises a first wall and a second wall separated longitudinally from one another along the longitudinal axis, and wherein a fuel injector passage is defined through the body coaxial to the longitudinal axis, and further wherein a plurality of vane walls is extended radially between the first wall and the second wall relative to the longitudinal axis, the plurality of vane walls being extended between and connected to the first wall and the second wall, and wherein a radial flow passage is extended between the plurality of vane walls and the fuel injector passage, the radial flow passage being defined by the plurality of vane walls, the first wall, and the second wall, and wherein an opening is defined at least partially through at least the first wall, the opening being in fluid communication with the radial flow passage and the opening extending radially from the fuel injector passage at least partially along a distance of the radial flow passage, such that the opening starts at an edge of the fuel injector passage and extends radially therefrom.

2. The flow device of claim 1 , wherein the opening is extended longitudinally through the first wall.

3. The flow device of claim 1 , wherein the opening is a circular or polygonal cross section through the first wall.

4. The flow device of claim 1 , wherein the radial flow passage is extended along a radial direction relative to the longitudinal axis from the fuel injector passage to a surrounding area radially outward of the body.

5. The flow device of claim 4 , wherein the body further comprises a third wall separated longitudinally from the second wall along the longitudinal axis, wherein a mixer assembly is positioned between the second wall and the third wall, the mixer assembly comprising a plurality of radially oriented vanes.

6. The flow device of claim 5 , wherein the mixer assembly defines a mixer flow passage extended radially, longitudinally, or both relative to the longitudinal axis.

7. The flow device of claim 1 , wherein the plurality of vane walls is in circumferential arrangement relative to the longitudinal axis.

8. The flow device of claim 1 , wherein the plurality of vane walls is extended at least partially tangentially relative to the longitudinal axis.

9. A combustor assembly for a combustion section, the combustor assembly defining a longitudinal axis along which a fuel injector is positioned, the combustor assembly comprising:
a flow device extended around the longitudinal axis, wherein the flow device comprises a first wall and a second wall separated longitudinally from one another along the longitudinal axis, and wherein a fuel injector passage is defined through the flow device coaxial to the longitudinal axis, and further wherein a plurality of vane walls is extended radially between the first wall and the second wall relative to the longitudinal axis, the plurality of vane walls being extended between and connected to the first wall and the second wall, and wherein a radial flow passage is extended between the plurality of vane walls and the fuel injector passage, the radial flow passage being defined by the plurality of vane walls, the first wall, and the second wall, and further wherein an opening is defined at least partially through at least the first wall, the opening being in fluid communication with the radial flow passage and the opening extending radially from the fuel injector passage at least partially along a distance of the radial flow passage, such that the opening starts at an edge of the fuel injector passage and extends radially therefrom.

10. The combustor assembly of claim 9 , wherein the opening is defined through the first wall in direct fluid communication with the radial flow passage.

11. The combustor assembly of claim 9 , wherein the opening is extended longitudinally through the first wall.

12. The combustor assembly of claim 9 , wherein the radial flow passage is extended along a radial direction relative to the longitudinal axis from the fuel injector passage to a surrounding area radially outward of the flow device.

13. The combustor assembly of claim 12 , wherein the flow device further comprises a third wall separated longitudinally from the second wall along the longitudinal axis, wherein a plurality of radially oriented vanes defining a fuel/air mixer assembly is positioned between the second wall and the third wall.

14. The combustor assembly of claim 13 , wherein a mixer flow passage is extended radially and longitudinally relative to the longitudinal axis between the second wall, the third wall, and the plurality of radially oriented vanes.

15. The combustor assembly of claim 13 , wherein the first wall, the second wall, and the third wall are each in serial arrangement along the longitudinal axis.

16. The combustor assembly of claim 9 , further comprising:
a fuel injector positioned in the fuel injector passage, wherein the plurality of vane walls is configured to provide a flow of fluid through the radial flow passage from a surrounding area radially outward of the flow device to the fuel injector passage.

17. A heat engine comprising the combustor assembly of claim 9 .
