  • Dragon-king extreme events as precursors for catastrophic transition 
    Premraj, D.; Suresh, K.; Pawar, S. A.; Kabiraj, L.; Prasad, A.; Sujith, R. I. (2021-11-27)
    Unexpected catastrophic transitions are often observed in complex systems. However, the prediction of such transitions is difficult in practice. Here, we find a special kind of extreme events with a dragon-king probability ...
  • Effect of phase-shift feedback on thermoacoustic coupling 
    Moran, B.M.; Saurabh, A.; Paschereit, C.O.; Kabiraj, L. (2019-01-02)
    The feedback interaction between unsteady heat release rate and combustor acoustics leading to self-excited oscillations is a well-known phenomenon, referred technically to as thermoacoustic instability. The phenomenon is ...
  • Fractal characteristics of combustion noise 
    Saurabh, A.; Imran, H.; Nawroth, H.; Paschereit, C. O.; Kabiraj, L. (2021-10-16)
    Fractal analysis is undertaken to characterize flame surface fluctuations on an unconfined turbulent premixed flame and the resulting far-field acoustics fluctuations. Results indicate that combustion noise is monofractal ...
  • A review on Noise-Induced dynamics of thermoacoustic systems 
    Kabiraj, L.; Vishnoi, N.; Saurabh, A. (2021-07-12)
    Practical combustion systems such as gas turbine combustors, rocket engines, industrial furnaces, and boilers are essentially thermoacoustic oscillators involving acoustic energy amplification through feedback interaction ...
  • Strange nonchaos in self-excited singing flames 
    Premraj, D.; Pawar, S. A.; Kabiraj, L.; Sujith, R. I. (2021-08-28)
    We report the first experimental evidence of a strange nonchaotic attractor (SNA) in the natural dynamics of a self-excited laboratory-scale system. In the previous experimental studies, the birth of a SNA was observed ...
  • System Parameter Identification of a Colored-Noise-Driven Rijke Tube Simulator 
    Vishnoi, N.; Gupta, V.; Saurabh, A.; Kabiraj, L. (2022-09-27)
    In this paper, we report an experimental investigation on the influence of colored noise (generated by the Ornstein–Uhlenbeck (OU) process) on thermoacoustic coupling in an electro-acoustic Rijke tube simulator. In the ...
