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 systems from time domain data

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 signal acquired in a combustor

An experimental investigation of the influence of dampers on the stability margin of an atmospheric lab-scale annular combustor is presented. The rig allows the comparison of different damper configurations regarding the number of dampers, their spat

The goal of the study presented in this paper is to analyze how the stability margin of a premixed combustor changes when liquid water is injected. Within the scope of this work, experimental results are presented and serve as a validation basis for

Water injection offers a high potential for raising the electrical power output of stationary gas turbines without drawbacks in emissions. To achieve that, liquid water is injected into the primary combustion zone of the flame while simultaneously re

The goal of the study presented in this paper is to analyze flame transfer functions with a new approach based on the combination of-line-of sight OH*-chemiluminescence and density fluctuation data. The OH*-chemiluminescence is acquired with a photom

In this study, we employ a method based on Bayesian statistics to determine the rate of acoustic decay from dynamic pressure measurements inside a combustor. It is common, that lean premixed flames tend to drive thermoacoustic instabilities at specif
