Modeling the influence of interactions on different variables in a turbulent thermoacoustic system
Aneesh Srivatsa, Shruti Tandon, Andrea Elizabeth Biju +3
Turbulent reacting flows confined to ducts are plagued by thermoacoustic instability, a state in which a positive feedback between flow, flame and acoustic perturbations leads to t…
Non-monotonic emergence of order from chaos in turbulent thermo-acoustic fluid systems
Aswin Balaji, Shruti Tandon, Norbert Marwan +2
Self-sustained order can emerge in complex systems due to internal feedback between coupled subsystems. Here, we present our discovery of a non-monotonic emergence of order amidst…
Cross-variable amplitude-frequency coupling during intermittency in a turbulent thermoacoustic system
Shruti Tandon, Aswin Balaji, Rohit Radhakrishnan +3
We investigate flame-acoustic interactions in a turbulent combustor during the state of intermittency before the onset of thermoacoustic instability using complex networks. Experim…
Emergence of order from chaos through a continuous phase transition in a turbulent reactive flow system
Sivakumar Sudarsanan, Amitesh Roy, Induja Pavithran +2
As the Reynolds number is increased, a laminar fluid flow becomes turbulent, and the range of time and length scales associated with the flow increases. Yet, in a turbulent reactiv…
