    • The Rayleigh integral is always positive in steadily operated combustors 

      Schuermans, Bruno; Moeck, Jonas; Blonde, Audrey; Dharmaputra, Bayu; Noiray, Nicolas (Peer reviewed; Journal article, 2022)
      The Rayleigh index has been used for decades by a large number of researchers as an indicator to determine if a flame is driving or damping thermoacoustic interaction mechanisms. The use of the Rayleigh criterion has found ...

    • Reduced-order modelling of thermoacoustic instabilities in can-annular combustors 

      Orchini, Alessandro; Pedergnana, Tiemo; Buschmann, Philip Erik; Moeck, Jonas; Noiray, Nicolas (Peer reviewed; Journal article, 2022)
      Thermoacoustic instabilities in stationary gas turbines may cause high-amplitude limit cycles, leading to damaged components and costly down-time. To better understand the physical origin of such instabilities in a can-annular ...
