Dynamics of coupled thermoacoustic oscillators under asymmetric forcing: Experiments and theoretical modeling
Ankit Sahay, Amitesh Roy, Samadhan A. Pawar +1
Quenching of limit cycle oscillations (LCO), either through mutual coupling or external forcing, has attracted wide attention in several fields of science and engineering. However,…
Critical region in the spatiotemporal dynamics of a turbulent thermoacoustic system and smart passive control
Amitesh Roy, C P Premchand, Manikandan Raghunathan +3
We develop a passive control strategy for suppressing thermoacoustic instability in a bluff-body stabilized premixed turbulent combustor. When the equivalence ratio is varied, ther…
Fractal dimension of premixed flames in multifractal turbulence
Amitesh Roy, R I Sujith
In turbulent premixed flames, the fractal dimension of flame iso-surface is argued to be for Damköhler's large-scale limit and for Damkö…
Flame dynamics during intermittency and secondary bifurcation to longitudinal thermoacoustic instability in a swirl-stabilized annular combustor
Amitesh Roy, Samarjeet Singh, Asalatha Nair +2
In this experimental study on a laboratory-scale turbulent annular combustor with sixteen swirl-stabilized burners, we study the flame-flame and flame-acoustic interactions during…
