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 …

A unique concept of utilizing localized surface compliance is proposed to suppress deep
cavity aeroacoustics at a low Mach number. The core idea is to provide local absorption of …

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 …

Computing sound, taking into account the dynamical phenomena leading to its generation
and transmission through fluid, is a challenging issue, with several applications into different …

This study examines an elastic panel flush-mounted on the bottom wall of a deep cavity,
under the subsonic flow condition of Mach number 0.09, as a passive approach to the tonal …

This paper reports a numerical study of a novel methodology for passive suppression of
deep cavity noise by means of strategically designed and arrangements of multiple elastic …

This study investigates a novel passive control technique for suppressing tonal noise in
deep cavities, focusing on the strategic use of surface compliance. An experimental setup …
