This paper provides a detailed historical review of the cavity flow phenomena in fluid
mechanics, from recorded studies in the late 19th century to more recent work. Research …

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 …

Insertion loss (IL) is a more useful acoustic index than noise reduction and transmission loss
for muffler design, but it is harder to predict because the prediction of IL requires knowing the …

An open rectangular cavity with a length to depth ratio of 2 (L/D= 2) and inlet Mach number
1.71 was considered as a baseline configuration for an unsteady computational analysis …

Flows past cavities at high-speeds have become increasingly important in applications such
as flame-holding and propulsion unstart control. Recently maturated linear techniques have …

A hydrodynamic and acoustic mode decomposition method for velocity and pressure based
on Helmholtz decomposition and momentum equation is proposed. It is able to decompose …

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 …

The dynamic characteristics of mode behavior in a low-speed, single-stage axial
compressor are crucial for studying linear stall inception. An input–output analysis …

A study with experimental and numerical components is conducted to establish the effect of
a two-dimensional surface cavity on the structure and growth rate of a turbulent spot. The …

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 …
