Abstract

A gas turbine engine (10) including a compressor section (12), a combustion section (14), and a turbine section (16) in serial flow arrangement, with the combustion section (14) having a fuel nozzle (101, 201, 301, 401, 501, 601, 701). The fuel nozzle (101, 201, 301, 401, 501, 601, 701) includes a fuel nozzle body (102, 302, 402, 502, 602, 702) defining a central channel (112, 312, 412, 512, 612, 712) comprising a compressed air passage (114, 314, 514, 614) and a mixing tube (116, 316, 516, 616), the fuel nozzle body (102, 302, 402, 502, 602, 702) defining a fuel nozzle centerline (104, 304, 404, 504, 604, 704). The fuel nozzle (101, 201, 301, 401, 501, 601, 701) includes an inner air flow path (134, 334, 335, 434, 534) supplying a first air flow (Ai) to the mixing tube (116, 316, 516, 616), an outer air flow path (138, 238, 338, 339, 438, 538, 638), circumscribing the inner air flow path (134, 334, 335, 434, 534), and supplying a second air flow (A₂) to the mixing tube (116, 316, 516, 616), a set of fluid diodes (140, 240, 340, 440, 540, 640, 740) including a subset (141, 241, 342, 343, 541, 647) of the set of fluid diodes (140, 240, 340, 440, 540, 640, 740) located within the outer air flow path (138, 238, 338, 339, 438, 538, 638) and generating a set of vortices within the outer air flow path (138, 238, 338, 339, 438, 538, 638), and a fuel supply (150, 350, 550, 650) including a set of fuel orifices (156, 556, 658) through which a fuel (F) flow is supplied to the mixing tube (116, 316, 516, 616).
