Cluster formation in particle-laden flows is a continuous phase transition
K Shri Vignesh, Shruti Tandon, Praveen Kasthuri +1
Studying particle-laden flows is essential to understand diverse physical processes such as rain formation in clouds, pathogen transmission, and pollutant dispersal. Distinct clust…
Control of growth of local heat release rate fluctuations to suppress thermoacoustic instability
M. Raghunathan, N. B. George, V. R Unni +3
This experimental study investigates the dynamical transition from stable operation to thermoacoustic instability in a turbulent bluff-body stabilized dump combustor. We conduct ex…
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…
