At speeds above 300–350 km/h, the main source of noise from trains is the aerodynamic
noise caused by the air flow over the train structure. The sound level increases with train …

This paper reviews previous studies on the flow around and flow-induced noise produced by
a finite wall-mounted cylinder (FWMC) of circular and square cross section. The flow around …

The unsteady flow separation and wake dynamics around finite wall-mounted circular
cylinders fully immersed in a turbulent boundary layer (TBL) are investigated experimentally …

The use of porous materials is one of several approaches to passively control or minimize
the generation of flow noise. In order to investigate the possible reduction of noise from …

This paper provides an experimental investigation of the noise generated from a blunt flat
plate and the possibility of the control of noise at source using porous trailing edges. The …

Different flow models have been proposed for the flow around surface-mounted finite-height
square prisms, but there is still a lack of consensus about the origin and connection of the …

At typical speeds of modern high-speed trains the aerodynamic noise produced by the
airflow over the pantograph is a significant source of noise. Although numerical models can …

This paper presents a combined experimental and large-eddy simulation study to
characterise the effect of aspect ratio on the near-wake structure of a square finite wall …

A wall-attached cube immersed in a zero pressure gradient boundary layer is studied by
means of Direct Numerical Simulations (DNS) at various Reynolds numbers Re H (based on …

This paper presents the results of an experimental study that relates the flow structures in the
wake of a square finite wall-mounted cylinder with the radiated noise. Acoustic and hot-wire …
