A network-theoretic approach for characterizing Mack-mode instability in high-speed boundary layers
Sai Prasad Mohanty, Nikhil Khobragade, Gaurav Chopra +3
Here we present a network theory-based approach to investigate the Mack-mode instability signature found in high-speed schlieren data from a Mach 6 laminar boundary layer flow over…

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…
