An aircraft in practice serves under extreme flight conditions that will have a substantial
impact on its flight safety. Understanding dynamics of airfoil structure of an aircraft subjected …

Abstract The Delayed Detached Eddy Simulation (DDES) and Ffowcs Williams–Hawkings
(FW–H) analogy have been performed to describe the unsteady flow and noise-generation …

To improve the current understanding of flap noise generation mechanisms in high-lift
devices used by small-to large-size commercial aircraft, a detailed study of both two-and …

The leading-edge slat of a multielement wing is a significant contributor to the acoustic
signature of an aircraft during the approach phase of the flight path. An experimental study of …

We investigate the slat narrowband peak noise generating mechanism. Unsteady flow data
were generated by a lattice-Boltzmann-based commercial code for four configurations …

Slat/fuselage juncture noise or slat horn noise has been identified as a major airframe noise
component and is commonly assumed to be similar to the flap side-edge noise. However …

Aeroacoustics is an interdisciplinary research field situated between aerodynamics and
acoustics. It focuses on understanding the sound generated by the motion of air around solid …

This paper assesses the comparability of aeroacoustic slat noise measurement in an open-
jet, a hard-wall, and a hybrid test section configuration. The 30P30N common research …

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 …

The flow around the slat cove of a two-dimensional 30P30N multi-element airfoil is
investigated with time-resolved particle image velocimetry (TR-PIV) at low Reynolds number …
