Abstract: A fuel distribution manifold for a combustor of a gas turbine includes an annular flange having an outer surface that extends circumferentially around the flange. A primary fuel plenum extends circumferentially within the flange. A first orifice and a second orifice extend radially through the outer surface of the flange to provide for fluid communication into the primary fuel plenum. The first orifice includes an inlet that is adjacent to the outer surface. The second orifice includes an inlet that is adjacent to the outer surface. A fuel distribution cap extends partially across the outer surface of the flange. The fuel distribution cap includes an inlet port. A fuel distribution plenum is at least partially defined within the fuel distribution cap. The fuel distribution plenum is in fluid communication with the inlet port and with the first orifice inlet and the second orifice inlet.

Abstract: A passive flow modulation device according to an embodiment includes: a pressure sensitive main valve controlling a flow of a cooling fluid from a first area to a second area through an orifice; and a temperature sensitive pilot valve coupled to the pressure sensitive main valve, the temperature sensitive pilot valve configured to open at a predetermined temperature in the first area, causing a pressurization of the pressure sensitive main valve, wherein the pressurization of the pressure sensitive main valve actuates the pressure sensitive main valve to an open position, allowing the cooling fluid to flow from the first area to the second area through the orifice.

Abstract: Airfoils including a plurality of nozzles and venturi. The airfoils may include a body including an inner wall defining a high pressure fluid chamber, and a plurality of high pressure nozzles extending through the inner wall. Each high pressure nozzle may be in fluid communication with the high pressure fluid chamber. The airfoil body may also include an intermediate wall positioned adjacent to and surrounding the inner wall to define a low pressure fluid chamber formed between the intermediate wall and the inner wall, and a plurality of low pressure venturi extending through the intermediate wall. Each low pressure venturi may be in fluid communication with the low pressure fluid chamber. Additionally, the airfoil body may include an outer wall positioned adjacent to and surrounding the intermediate wall to define a cooling channel formed between the intermediate wall and the outer wall.
