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 a cavity flow with acoustic radiation, self-sustained oscillations are controlled by a
continuously or intermittently driven plasma actuator with elongated electrodes in the …

On the reduction of equivalence ratio from stoichiometry to lean conditions, turbulent
combustors exhibit intermittency before and after the occurrence of thermoacoustic …

The characteristics of supersonic cavity flows were investigated using large eddy simulation
together with the acoustic analogy method. A fifth-order hybrid compact-weighted essentially …

To clarify fluid–acoustic interactions in an actual recorder with opened and closed tone
holes, flow and acoustic fields were directly numerically simulated on the basis of the …

Recently, there has been a growing interest in understanding and characterising intermittent
burst oscillations that presage the onset of combustion instability. We construct a …

Microphone measurements in a closed test section wind tunnel are affected by turbulent
boundary layer (TBL) pressure fluctuations. These fluctuations are mitigated by placing the …

Implicit large-eddy simulations are performed to investigate the acoustic resonances from a
leading-edge slat at two different Reynolds numbers. Three types of acoustic waves are …

Computations of coupled phenomena between the fluid and acoustic interactions in the
cavity flow and heat conduction in the flat plates (stack) installed in the cavity were …

The sound generation mechanisms of sibilant fricatives were investigated with experimental
measurements and large-eddy simulations using a simplified vocal tract model. The vocal …
