Aero-engine noise reduction has always been a critical challenge in the field of science and
engineering. Passive acoustic liners are considered one of the most effective structures for …

We present pore-resolved compressible direct numerical simulations of turbulent flows
grazing over perforated plates, that closely resemble the acoustic liners found on aircraft …

Nacelle acoustic liners inevitably generate greater aerodynamic drag than smooth walls. It is
necessary to study the factors influencing acoustic liner drag to reduce engine fuel …

Pore-resolved direct numerical simulations (DNS) of turbulent flows grazing over acoustic
liners with aerodynamically and/or acoustically optimized orifice configurations are …

Shorter engine inlets and more compact nacelles are being considered to reduce weight
and drag of future commercial airplanes. Such designs may have significantly less area for …

A turbulent boundary layer is a ubiquitous element of fundamental and applied fluid
mechanics. Unfortunately, accurate measurements of turbulent boundary layer parameters …

Recently, the aerodynamic performance of acoustic liners has become a research focus. It is
necessary to study the influencing factors of the acoustic liner drag to further reduce engine …

We aim to reduce aerodynamic drag over an acoustic liner, which comprises of a perforated
plate, a honeycomb core, and a rigid backplate, for aero-engine applications through both …
