This study presents the interplay of flow and acoustics within tandem deep cavities, focusing
on the resonance mechanism occurring between turbulent shear layers and acoustic …

In this work, the classic problem of the aeroacoustic instability occurring in deep cavities
subject to a low-Mach grazing flow is revisited experimentally and theoretically. This …

In this paper, we study the aeroacoustic instability which occurs in a deep axisymmetric
cavity in a turbulent pipe flow. This phenomenon is the axisymmetric counterpart of the …

Interference with a nonlinear cavity mode undergoing a self-sustained limit cycle can lead to
superradiant amplification of incident waves. This effect, which results from nonlinear wave …

Thermoacoustic instabilities in stationary gas turbines may cause high-amplitude limit
cycles, leading to damaged components and costly down-time. To better understand the …

The whistling induced by a low-Mach turbulent flow through a deep axisymmetric cavity in a
duct is investigated theoretically and experimentally. The experiments include acoustic …

Thermoacoustic instabilities in can-annular combus-tors of stationary gas turbines lead to
unstable Bloch modes which appear as rotating acoustic pressure waves along the turbine …

Hydrodynamic modes in the turbulent mixing layer over a cavity can constructively interact
with the acoustic modes of that cavity and lead to aeroacoustic instabilities. The resulting …

Networks of coupled nonlinear oscillators model a broad class of physical, chemical and
biological systems. Understanding emergent patterns in such networks is an ongoing effort …

Aeroacoustic feedback loops can occur in a variety of flows: high speed jets interacting with
a plate or a corner, supersonic non-ideally expanded free jets, grazing flow over a cavity …
