Abstract: In this paper, we present a method to determine the quantitative stability level of a lean-premixed combustor from dynamic pressure data. Specifically, we make use of the autocorrelation function of the dynamic pressure ...

Abstract: The goal of this study is to analyze flame transfer functions (FTFs) locally by quantifying the heat release rate with OH*chemiluminescence and density fluctuation measurements using laser vibrometry. In this study, both ...

Abstract: This paper presents a set of methodologies for the extraction of linear growth and damping rates associated with transversal eigenmodes at screech level frequencies in thermoacoustically noncompact gas turbine combustion ...
