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…

Identifying optimal location for control of thermoacoustic instability through statistical analysis of saddle point trajectories

C. P. Premchand, Abin Krishnan, Manikandan Raghunathan +4

We propose a framework of Lagrangian Coherent Structures (LCS) to enable passive open-loop control of tonal sound generated during thermoacoustic instability. Experiments were perf…

Dynamics of Minimal Networks of Limit Cycle Oscillators

Andrea Elizabeth Biju, Sneha Srikanth, Krishna Manoj +2

The framework of mutually coupled oscillators on a network has served as a convenient tool for investigating the impact of various parameters on the dynamics of real-world systems.…

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…

Evolution of clusters of turbulent reattachment due to shear layer instability in flow past a circular cylinder

Gaurav Chopra, Sanjay Mittal, R. I. Sujith

We perform large eddy simulations of flow past a circular cylinder for the Reynolds number () range, , spanning subcritical, critical and…

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…
