Geometric model of pantographs in high-speed trains.

Download scientific diagram | Geometric model of pantographs in high-speed trains. from publication: Numerical Modeling and Investigation on Aerodynamic Noise Characteristics of Pantographs in High-Speed Trains | Pantographs are important devices on high-speed trains. When a train runs at a high speed, concave and convex parts of the train cause serious airflow disturbances and result in flow separation, eddy shedding, and breakdown. A strong fluctuation pressure field will be caused | Aerodynamics, Noise and Training | ResearchGate, the professional network for scientists.
