- Tuned Passive Control of Combustion Instabilities Using Multiple Helmholtz Resonators (2007, background): “The frequencies of combustion instabilities tend to be close to the acoustic resonance frequencies of the combustion system, with the pressure oscillations occurring in the corresponding mode shape [17].”
- Solution of the quasi-one-dimensional linearized Euler equations using flow invariants and the Magnus expansion (2013, background): “If this fluctuating heat release and the acoustic waves are in phase, a positive feedback will occur as shown by Rayleigh (1878), Dowling (1997) and Dowling & Stow (2003).”
- Thermoacoustic Instability Considerations for High Hydrogen Combustion in Lean Premixed Gas Turbine Combustors: A Review (2021, background): “Following the onset of combustion instability, the amplitude of the pressure oscillations initially grows with time at an exponential rate in the linear regime before saturating into a finite amplitude limit cycle oscillation which arises from nonlinear effects [50].”
- Combining a Helmholtz solver with the flame describing function to assess combustion instability in a premixed swirled combustor (2013, background): “In a second step, this function can be combined to a model of the system acoustics which is often obtained analytically (Dowling and Stow, 2003; Sattelmayer and Polifke, 2003; Poinsot and Veynante, 2005).”
- Time domain simulations of nonlinear thermoacoustic behaviour in a simple combustor using a wave-based approach (2015, methodology): “The transfer function is then combined with the acoustic response of the combustion chamber to analyse thermoacoustic stability and predict the eigenfrequencies and corresponding growth rates of potential instabilities [23,24].”
