Combining a Helmholtz solver with the flame describing function to assess combustion instability in a premixed swirled combustor (2013, methodology): “This is illustrated by analyzing the swirled burner dynamics considered by Palies et al. (2011a).”
Sensitivity and Nonlinearity of Thermoacoustic Oscillations (2018, background): “, 2015), and turbulent premixed or partially-premixed swirling flames (Bellows et al., 2007; Shreekrishna et al., 2010; Palies et al., 2011; Schimek et al., 2011; Krediet et al., 2012; Ćosić et al., 2014).”
Time domain simulations of nonlinear thermoacoustic behaviour in a simple combustor using a wave-based approach (2015, methodology): “This method can explain phenomena such as “hysteresis”, “triggering”, “mode switching”, frequency shift during the growth of instabilities and two mode limit cycles [30,43,42,45].”
Dynamics and control of premixed combustion systems based on flame transfer and describing functions (2020, background): “Effects of finite levels of oscillation are documented for example in Noiray et al. (2008); Palies et al. (2011); Krebs et al. (2013); Ghirardo et al. (2016); Larea et al. (2017).”
