A combustor liner assembly includes a liner assembly, including a hot dome, a hot wall, and an impingement shield. The liner assembly further includes a convector assembly. The combustor liner assembly further includes an impingement dome assembly, including a ring-shaped portion defining a plurality of apertures configured to receive a plurality of fuel injectors, and a face. The ring-shaped portion and the face define an annular passage, and the face defines a plurality of apertures and a plurality of orifices. The convector assembly and the impingement dome assembly are operably coupled to one another, and the plurality of orifices of the face are configured such that the hot dome is exposed to air flowing in the annular passage of the impingement dome assembly. The combustor liner assembly is configured to provide flow communication between the annular passage of the impingement dome assembly and the plurality of fuel injectors.

An injector for a gas turbine combustor including a catalyst coated surface forming a passage for feed gas flow and a channel for oxidant gas flow establishing an axial gas flow through a flow conditioner disposed at least partially within an inner wall of the injector. The flow conditioner includes a length with an interior passage opening into upstream and downstream ends for passage of the axial gas flow. An interior diameter of the interior passage smoothly reduces and then increases from upstream to downstream ends.

To meet emissions standards, many gas turbine engines use some form of lean, pre-mixed combustion system. The lean nature of the fuel may lead to combustion oscillations or other instabilities. A fuel injector having an inner and outer cylinder receives pilot fuel and a portion of pre-mixed fuel-air into an annular space defined by the inner and outer cylinders. The amount of pilot fuel mixed with the pre-mixed fuel-air can be modulated based on sensed conditions within the turbine engine. Continuous modulation of the pilot fuel to adapt to the sensed conditions improves main burner flames and response to engine transients.

Many government entities regulated emission from gas turbine engines including CO. CO production is generally reduced when CO reacts with excess oxygen at elevated temperatures to form CO2. Many manufactures use film cooling of a combustor liner adjacent to a combustion zone to increase durability of the combustion liner. Film cooling quenches reactions of CO with excess oxygen to form CO2. Cooling the combustor liner on a cold side (backside) away from the combustion zone reduces quenching. Furthermore, placing a plurality of concavities on the cold side enhances the cooling of the combustor liner. Concavities result in very little pressure reduction such that air used to cool the combustor liner may also be used in the combustion zone. An expandable combustor housing maintains a predetermined distance between the combustor housing and combustor liner.

Investigating the permeability and porosity of geological samples is a routine element of geological studies, and is of particular interest in the oil and gas industry. Core-flood experiments are commonly performed on rock samples to measure transport characteristics in the laboratory. This disclosure reports the design and implementation of a high resolution distributed pressure measurement system for core-flood experiments. A series of microfabricated pressure sensors can be embedded in bolts that are housed within the pressurized polymer sheath that encases a rock core. A feedthrough technology has been developed to provide lead transfer between the sensors and system electronics across a 230-bar pressure difference. The system has been successfully benchtop tested with fluids such as synthetic oil and/or gas. Pressure measurements were recorded over a dynamic range of 20 bar with a resolution as small as 0.3 mbar.
