Acoustic resonance induced by vortex sound interaction in a confined space could cause
both noise pollution and acoustic fatigue issues. The mechanism of vortex sound interaction …

Small axial fans, commonly employed for cooling electronic equipment, are frequently
housed within narrow ducts, where intense tonal sound with duct resonance can occur …

Small axial fans are used for cooling electronic equipment and are often installed in a casing
with various slits. Direct aeroacoustic simulations and experiments were performed with …

A fricative consonant (eg,[s]) is known to be pronounced by a turbulent jet flow inside the
oral cavity. In this study, the effects of tongue motion on the aeroacoustic sound generation …

A nonlinear model is developed to investigate the blade vibration-induced acoustic
resonance in a linear cascade. The Euler equations are solved by using high-order …

Direct aeroacoustic simulations of flow and sound around an instrument with an oscillating
reed were performed on the basis of compressible Navier–Stokes equations along with …

In order to better understand the noise generation mechanism of air outlets in an HVAC
(Heating Ventilation Air Conditioning) system of a car, investigations were performed in a …

Broadband noise due to the turbulence-aerofoil interaction, which is also called the leading
edge noise, is one of the major noise sources of aircraft (including the engine). To study the …

Featured Application Micro air vehicles. Abstract During insect flight, a feathering motion of
the wing's controls vortex shedding for lift enhancement. In this study, in order to control the …

This paper presents an efficient sliding mesh method to simulate the noise emission from
aero-engines. The vortexes shed from the rotating blade and interact with the downstream …
