This paper discusses the structural changes observed in oscillating premixed turbulent
swirling flames and demonstrates the influence of modulated mass flows on the flame …

Lean premixed combustors are highly susceptible to combustion instabilities, caused by the
coupling between heat release fluctuations and combustor acoustics. In order to predict the …

Velocity fields and flame structures of a partially premixed swirl flame in a gas turbine model
combustor are measured in axial and transverse sections using simultaneous (Stereo-) PIV …

Combustion instabilities represent a long known problem in combustion technology. The
complex interactions between acoustics and turbulent swirling flames are not fully …

This paper reports an experimental investigation of dynamic response of nonpremixed
atmospheric swirling flames subjected to external, longitudinal acoustic excitation. Acoustic …

Due to stringent emission restrictions, modern gas turbines mostly rely on lean premixed
combustion. Since this combustion mode is susceptible to thermoacoustic instabilities, there …

The Turbomeca gas turbine model combustor was studied to understand the effect of
increased thermal power density on the structure and dynamics of premixed swirl flames …

In this work, the Turbomeca (Preccinsta) gas turbine model combustor was used to study the
affects of increased thermal load on the premixed swirl flame behavior. The burner was …

The frequency response of premixed swirled flames is investigated by comparing their
Transfer Function (FTF) between velocity and heat release rate fluctuations. The …

The prevalence of gas turbines operating in primarily lean premixed modes is predicated on
the need for lower emissions and increased efficiency. An enhancement in the mixing …
