Identifying feedback directions in the mechanisms driving self-sustained thermoacoustic instability in a single-element rocket combustor
Somnath De, Praveen Kasthuri, Matthew E. Harvazinski +3
The occurrence of high frequency (>1000 Hz) thermoacoustic instability (TAI) sustained by mutual feedback among the acoustic field, heat release rate oscillations, and hydrodynamic…
Canard explosions in turbulent thermo-fluid systems
Ramesh S. Bhavi, Sivakumar Sudarsanan, Manikandan Raghunathan +2
A sudden transition to a state of high amplitude limit cycle oscillations is catastrophic in a thermo-fluid system. Conventionally, upon varying the control parameter, a sudden tra…
Explosive synchronization in a turbulent reactive flow system
Amal Joseph, Induja Pavithran, R. I. Sujith
The occurrence of abrupt dynamical transitions in the macroscopic state of a system has received growing attention. We present experimental evidence for abrupt transition via explo…
Universality of oscillatory instabilities in fluid mechanical systems
Vladimir Garcia-Morales, Shruti Tandon, Juergen Kurths +1
Oscillatory instability (OI) emerges amidst turbulent states in experiments in various turbulent fluid and thermo-fluid systems such as aero-acoustic, thermoacoustic and aeroelasti…
Spatiotemporal Patterns Corresponding to Phase Synchronization and Generalized Synchronization States of Thermoacoustic Instability
Samadhan A. Pawar, P. R. Midhun, K. V. Reeja +3
Thermoacoustic instability in turbulent combustion systems emerges from the complex interplay among the flame, flow, and acoustic subsystems. While the onset of thermoacoustic inst…
Frequency shifts during whistling occurs as transition between two phase synchronised limit cycles via a state of intermittency or abruptly
Ramesh S. Bhavi, Induja Pavithran, R. I. Sujith
Self-sustained oscillations arising from the interactions between the hydrodynamic and the acoustic field are disastrous in engineering systems such as segmented solid rocket motor…
