Insights of Transitions to Thermoacoustic Instability in Inverse Diffusion Flame using Multifractal Detrended Fluctuation Analysis
Somnath De, Soham Bhattacharya, Arijit Bhattacharya +3
The inverse diffusion flame (IDF) can experience thermoacoustic instability due to variations in power input or flow conditions. However, the dynamical transitions in IDF that lead…

Identifying feedback directions in the mechanisms driving self-sustained thermoacoustic instability in a single-element rocket combustor
Somnath De, Praveen Kasthuri, Matthew E. Harvazinski +3
The occurrence of high frequency (>1000 Hz) thermoacoustic instability (TAI) sustained by mutual feedback among the acoustic field, heat release rate oscillations, and hydrodynamic…
