Thonti B, Tandon S, Durairaj P, Sujith R
Chaos
. 2024 Dec;
34(12).
PMID: 39621475
We discover strange nonchaotic attractor (SNA) through experiments in an unforced system comprising turbulent reactive flow. While models suggest SNAs are common in dynamical systems, experimental observations are primarily limited...

Bhavi R, Sudarsanan S, Raghunathan M, Bhaskaran A, Sujith R
Chaos
. 2024 Oct;
34(10).
PMID: 39432718
A sudden transition to a state of high-amplitude periodic oscillations is catastrophic in a thermo-fluid system. Conventionally, upon varying the control parameter, a sudden transition is observed as an abrupt...

Chopra G, Unni V, Venkatesan P, Vallejo-Bernal S, Marwan N, Kurths J, et al.
Sci Rep
. 2024 Oct;
14(1):24463.
PMID: 39424906
The Intertropical Convergence Zone (ITCZ) is a narrow tropical belt of deep convective clouds, intense precipitation, and monsoon circulations encircling the Earth. Complex interactions between the ITCZ and local geophysical...

Premchand C, Krishnan A, Raghunathan M, Midhun P, Reeja K, Sujith R, et al.
Chaos
. 2024 Aug;
34(8).
PMID: 39141789
We propose a framework of Lagrangian Coherent Structures (LCSs) to enable passive open-loop control of tonal sound generated during thermoacoustic instability. Experiments were performed in a laboratory-scale bluff-body stabilized turbulent...

Sudarsanan S, Roy A, Pavithran I, Tandon S, Sujith R
Phys Rev E
. 2024 Jul;
109(6-1):064214.
PMID: 39020933
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 reactive...

Dhadphale J, Hauke Kraemer K, Gelbrecht M, Kurths J, Marwan N, Sujith R
Chaos
. 2024 Jul;
34(7).
PMID: 38985968
Phase space reconstruction (PSR) methods allow for the analysis of low-dimensional data with methods from dynamical systems theory, but their application to prediction models, such as those from machine learning...

Pawar S, Raghunath M, K Valappil R, Krishnan A, Manoj K, Sujith R
Chaos
. 2024 May;
34(5).
PMID: 38717395
Thermoacoustic instability in turbulent combustion systems emerges from the complex interplay among the flame, flow, and acoustic subsystems. While the onset of thermoacoustic instability exhibits a global order, the characteristics...

Joseph A, Pavithran I, Sujith R
Chaos
. 2024 Feb;
34(2).
PMID: 38412535
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 explosive synchronization in a real-world...

Chaos
. 2024 Jan;
34(1).
PMID: 38198675
Real-world complex systems such as the earth's climate, ecosystems, stock markets, and combustion engines are prone to dynamical transitions from one state to another, with catastrophic consequences. State variables of...

Chaos
. 2023 Dec;
33(8).
PMID: 38060796
Abrupt changes in the state of a system are often undesirable in natural and human-made systems. Such transitions occurring due to fast variations of system parameters are called rate-induced tipping...
