Abstract: Understanding the effects of inlet velocity and inlet equivalence ratio fluctuations on heat release rate fluctuations in lean premixed gas turbine combustors is essential for predicting combustor instability characteristics. ...

Abstract: Flame response to imposed velocity fluctuations is experimentally measured in a singlenozzle turbulent swirling fullypremixed combustor. The flame transfer function is used to quantify the flame's response to imposed ...

Abstract: A tomographic image reconstruction technique has been developed to measure the 3D distribution of CH* chemiluminescence of unforced and forced turbulent premixed flames. Measurements are obtained in a lean premixed, ...

Abstract: Fluctuations in the heat release rate that occur during unstable combustion in leanpremixed gas turbine combustors can be attributed to velocity and equivalence ratio fluctuations. For a fully premixed flame, velocity ...

Abstract: The effect of flame–wall interactions on the forced response of a leanpremixed, swirlstabilized flame is experimentally investigated by examining flames in a series of three combustors, each with a different diameter, ...

Abstract: Flame structure can have a significant effect on a combustor's static stability (resistance to blowoff) and dynamic stability (combustion instability) and therefore is an important aspect of the combustion process that ...

Abstract: Fuel staging is a commonly used strategy in the operation of gas turbine engines. In multinozzle combustor configurations, this is achieved by varying fuel flow rate to different nozzles. The effect of fuel staging on flame ...

Abstract: The effect of confinement (flame–wall interactions) on the response of a turbulent, swirl-stabilized flame is experimentally examined, with a focus on the shape and structure of these flames. A series of three cylindrical ...
