Study on the aerodynamic noise characteristics of high-speed pantographs with different strip spacings

Journal of Wind Engineering and Industrial Aerodynamics, 2020
In order to study the effect of the strip spacing on the aerodynamic noise characteristics of the pantograph of high-speed train, the numerical simulation of the aerodynamic flow behavior for the high-speed pantograph is conducted using the detached eddy

Aerodynamic noise reduction of circular cylinder by longitudinal grooves

Journal of Wind Engineering and Industrial Aerodynamics, 2020
Aerodynamic noise reduction of a circular cylinder using longitudinal grooves was experimentally investigated by measuring noise and velocity fields with a microphone and particle image velocimetry, respectively. Experiments were performed in an acoustic
