Automotive aeroacoustics: An overview [PDF]
Proceedings of the Institution of Mechanical Engineers, Part D: Journal of Automobile Engineering, 2017 Vehicle aeroacoustic performance has a major influence on customer perception and also has importance for safety and comfort. Wind noise performance was once differentiated by the quality of sealing. Today, achieving competitive wind noise performance also depends on minimising aeroacoustic noise sources generated by the vehicle form, and on ...

Hybrid Computation of the Aerodynamic Noise Radiated by the Wake of a Subsonic Cylinder
Fluids, 2023 The noise radiated by the flow around a cylinder in the subcritical regime at ReD=1×104 and at a subsonic Mach number of M=0.5 is here studied. The aerodynamic sound radiated by a cylinder has been studied with a wide range of Reynolds numbers, but there

Comparison of outflow boundary conditions for subsonic aeroacoustic simulations [PDF]
, 2011 Aeroacoustics simulations require much more precise boundary conditions than classical aerodynamics. Two classes of non-reflecting boundary conditions for aeroacoustics are compared in the present work: characteristic analysis based methods and Tam and ...
