HIGHLIGHTS
- who: Hogun Kim from the University of Southampton, Southampton , BJ, UK have published the Article: Effect of cavity flow control on high-speed train pantograph and roof aerodynamic noise, in the Journal: (JOURNAL)
- what: In this paper the flow features and noise contribution of two types of noise reduction treatments rounded and chamfered edges are studied for a simplified high-speed train pantograph recess which is represented as a rectangular cavity and numerically investigated at 1/10 scale. This study shows that by rounding the cavity edges a reduction in radiated noise at the side . . .
