Performance and Efficiency of Cross-Flow Fans—A Review
Energies, 2023 Cross-Flow Fans (CFFs) have been widely applied in the automotive and domestic air conditioning industries in recent decades. They are high-pressure coefficient turbomachines compacted diametrically, and thus, the complex interactions of these fans ...

Aeroacoustic performance of a scoop inlet [PDF]
4th Aeroacoustics Conference, 1977 A low speed wind tunnel test demonstrated the aerodynamic and acoustic performance of a scoop inlet. Engine noise is directed upward by the extended lower lip of the scoop inlet. In addition, more of the scoop airflow comes in from above the inlet than below, leading to relatively higher surface velocities on the upper lip and lower surface velocities ...

Assessing the Aeroacoustic Response of a Vehicle to Transient Flow Conditions from the Perspective of a Vehicle Occupant [PDF]
, 2014 On-road, a vehicle experiences unsteady flow conditions due to turbulence in the natural wind, moving through the unsteady wakes of other road vehicles and travelling through the stationary wakes generated by roadside obstacles. Separated flow structures

Design and performance of an open jet wind tunnel for aero-acoustic measurement [PDF]
, 2009 This paper presents the design and performance of an open jet, blow down wind tunnel that was newly commissioned in the anechoic chamber at the ISVR, University of Southampton, UK. This wind tunnel is intended for the measurement of airfoil trailing edge

Aerodynamic and Aeroacoustic Performance of Serrated Airfoils
21st AIAA/CEAS Aeroacoustics Conference, 2015 The aerodynamic and aeroacoustic performance of serrated airfoils have been studied experimentally. A comprehensive aerodynamic study of a symmetric (NACA 0012) and an asymmetric (NACA 65(12)-10) airfoil with different types of trailing-edge serrations has been performed.

On the aeroacoustic properties of a beveled plate
E3S Web of Conferences, 2015 The flow around a beveled flat plate model with an asymmetric 25 degrees trailing edge with three rounding radii is analyzed using a Navier-Stokes based open source software package OpenFOAM in order to predict the aeroacoustic properties of the models ...

Large-Eddy Simulation of the Aerodynamic and Aeroacoustic Performance of a Ventilation Fan [PDF]
Advances in Acoustics and Vibration, 2013 There are controversial requirements involved in developing numerical methodologies in order to compute the flow in industrial fans. The full resolution of turbulence spectrum in such high-Reynolds number flow configurations entails unreasonably expensive computational costs.
