The aerodynamic characteristics of a conventional line pantograph in a crosswind were investigated by conducting large-eddy simulations (LESs). In a previous study, wind tunnel tests using a full-scale pantograph were performed at various attack angl

Toward an advanced high-speed railway system, there are ongoing extensive studies on both of railway vehicles and infrastructures. Reducing the aerodynamic noise emitted from the pantograph heads is one of the most important subjects for high-speed r

It is necessary for pantographs of Japanese high-speed trains to satisfy both low noise characteristics and insensitive lift force characteristics toward the variation in wind direction and in the shape of pantograph head due to wear. Taking particul

A vortex generator (VG) is one of the most successful devices used for suppression of flow separation. A conventional VG is a passive control device, so that it may suffer from an inherent drag penalty. As an alternative, we use a dielectric-barrier-
