Definitions
- the present disclosure relates generally to a turbine engine, and more particularly, to a turbine engine having an acoustically tuned fuel nozzle.
- Internal combustion engines including diesel engines, gaseous-fueled engines, and other engines known in the art, may exhaust a complex mixture of air pollutants.
- air pollutants may be composed of gaseous compounds, which may include nitrous oxides (NOx).
- NOx nitrous oxides Due to increased attention on the environment, exhaust emission standards have become more stringent and the amount of NOx emitted to the atmosphere from an engine may be regulated depending on the type of engine, size of engine, and/or class of engine.
- a well-distributed flame having a low flame temperature can reduce NOx production to levels compliant with current emission regulations.
- One way to generate a well-distributed flame with a low flame temperature is to premix fuel and air to a predetermined lean fuel to air equivalence ratio.
- naturally-occurring pressure fluctuations within the turbine engine can be amplified during operation of the engine under these lean conditions. In fact, the amplification can be so severe that damage and/or failure of the turbine engine can occur.

- FIG. 3 illustrates an exemplary relationship between the length of air inlet duct 35 , the length of mixing duct 37 , the axial fuel introduction point within barrel housing 34 resulting from the position of swirler 40 along common axis 42 , and the naturally-occurring pressure fluctuation stemming from a flame front 67 within combustion chamber 28 .
- FIG. 3 will be discussed in more detail below.
- the disclosed fuel nozzle may be applicable to any turbine engine where reduced vibrations within the turbine engine are desired. Although particularly useful for low NOx-emitting engines, the disclosed fuel nozzle may be applicable to any turbine engine regardless of the emission output of the engine. The disclosed fuel nozzle may reduce vibrations by acoustically attenuating a naturally-occuring pressure fluctuation within a combustion chamber of the turbine engine. The operation of fuel nozzle 26 will now be explained.
- air may be drawn into turbine engine 10 and compressed via compressor section 12 (referring to FIG. 1 ). This compressed air may then be axially directed into combustor section 14 and against vanes 54 of swirler 40 , where the flow may be redirected radially inward.

- FIG. 3 illustrates the time-varying flow characteristics of fuel and air entering fuel nozzle 26 and their effects on the naturally-occuring pressure fluctuations within combustion chamber 28 .
- FIG. 3 illustrates a first curve 60 , a second curve 62 , a third curve 64 , and a plurality of pressure pulses 66 .
- First curve 60 may represent the time-varying flow of compressed air entering fuel nozzle 26 via air inlet duct 35 .
- Second curve 62 may represent the time-varying flow of fuel flow entering fuel nozzle 26 via liquid and/or gaseous fuel jets 56 , 58 .
- Third curve 64 may represent the time-varying fuel to air equivalence ratio ⁇ (e.g., the instantaneous ratio of the amount of fuel within any axial plane along the length of fuel nozzle 26 to the amount of air in the same axial plane).
- Pressure pulses 66 may represent a wave of pressure traveling from combustion chamber 28 in a reverse direction toward air inlet duct 35 as a result of combustion within combustion chamber 28 .
- Pressure pulses 66 may affect the time-varying characteristic of first, second, and third curves 60 - 64 . Specifically, as pressure pulses 66 travel in the reverse direction within fuel nozzle 26 and reach liquid and gaseous fuel injectors 56 , 58 and the entrance to air inlet duct 35 , the pressure of each pulse may cause the flow rate of fuel and air entering fuel nozzle 26 to vary. These varying flow rates correspond to the amplitude variations of first and second curves 60 , 62 illustrated in FIG. 3 , which equate to the varying amplitude and phase angle of third curve 64 . When the value of ⁇ at the point of combustion within combustion chamber 28 is high compared to a time average value of ⁇ , the heat release and resulting pressure wave within combustion chamber 28 may be high. Likewise, when the value of ⁇ at the point of combustion within combustion chamber 28 is low compared to the time average value of ⁇ , the heat release and resulting pressure wave within combustion chamber 28 may be low.
- Damage may occur when the phase angle of third curve 64 and the wave of pressure pulses 66 near alignment. That is, when the value of ⁇ entering combustion chamber 28 is high compared to the time average of ⁇ and enters combustion chamber 28 at about the same time that a pressure pulse 66 initiates from a flame front with combustion chamber 28 , resonance may be attained. Likewise, if the value of ⁇ entering combustion chamber 28 is low compared to the time average of ⁇ and enters combustion chamber 28 at a time between the intiation of pressure pulses 66 , resonance may be attained. It may be possible that this resonance could amplify pressure pulses 66 to a damaging magnitude.
- Damage may be prevented when third curve 64 and the wave of pressure pulses 66 are out of phase.
- the value of ⁇ entering combustion chamber 28 is low compared to the time average of ⁇ and enters combustion chamber 28 at the same time that a pressure pulse 66 initiates from a flame front within combustion chamber 28 , attenuation of pressure pulse 66 may be attained.
- the value of ⁇ entering combustion chamber 28 is high compared to the time average of ⁇ and enters combustion chamber 28 at a time between the imitation of pressure pulses 66 , attenuation may be attained. Attenuation could lower the magnitude of pressure pulses 66 , thereby minimizing the likelihood of damage to turbine engine 10 .
- the phase angle and magnitude of ⁇ may be affected by the length of air inlet duct 35 , the length of mixing duct 37 , the axial fuel introduction point, and the axial location of air jets 46 .
- the phase angle of first curve 60 may likewise shift to the left.
- the phase angle of first curve 60 may likewise move to the right.
- first and second curves 60 , 62 may be nearly zero, resulting in a substantially constant value of ⁇ .
- the phase angle of first curve 60 may move to the left.
- decreasing the length of mixing duct 37 e.g., moving the exit of mixing duct 37 leftward, when viewed in FIG.
- the phase angle of first curve 60 may move to the right.
- the phase angle of second curve 62 may mimic the same shifts.
- the phase angle and amplitude of third curve 64 may be affected.
- the value of ⁇ entering combustion chamber 28 can be acoustically tuned to attenuate the naturally-occuring pressure pulses 66 of a specific engine or specific class or size of engine. It is contemplated that only one or both of the lengths of air inlet duct 35 and mixing duct 37 may be modified to attenuate the naturally-occurring pressure pulses 66 .
- Further reduction in the magnitude of pressure pulses 66 may be attained by providing a substantially time-constant value of ⁇ .
- One way to reduce the variation in the value of ⁇ may be to reduce the time-varying characteristic of first and/or second curves 60 , 62 .
- the time-varying characteristic of gaseous fuel introduced into combustion chamber 28 via gaseous fuel jets 58 may be reduced by way of the restriction at the surface of gaseous fuel jets 58 . This restriction may increase the pressure drop across gaseous fuel jets 58 to a magnitude at which the pressure fluctuations within fuel nozzle 26 may have little affect on the flow of fuel through gaseous fuel jets 58 .
- Another way to reduce the vibrations may be realized through the use of air jets 46 . In particular, as seen in FIG.
- the pulses of compressed air may be injected by air jets 46 substantially 180 degrees out of phase with first curve 60 .
- the affect of the injected pulses of air can be seen in FIG. 3 ; as the flow of compressed air entering barrel housing 34 via air inlet duct 35 passes in proximity to air jets 46 , the amplitude of first curve 60 may be reduced.
