Shock-induced tipping in a thermoacoustic system
Bhadra Sreelatha, Rohit Radhakrishnan, R. I. Sujith
Tipping refers to the transition of a system from one state to another. In this study, we focus on shock-induced tipping, which occurs due to a sudden and large disturbance in a co…

Vortical interactions in turbulent thermoacoustic systems
Ankit Sahay, Muralikrishnan Gopalakrishnan Meena, R. I. Sujith
This study examines the dynamics of vortical interactions and their implications for mitigating thermoacoustic instability in a turbulent combustor. The regions of intense vortical…
