Abstract:A pantograph serves as a vital device for the collection of electricity in trains. However, its aerodynamic resistance can limit the train's running speed. As installing fairings around the pantograph is known to effectively reduce the resistance, in this study, different fairing lengths are considered and the related aerodynamic performances of pantograph are assessed. In particular, this is accomplished through numerical simulations based on the k-ω Shear Stress Transport (SST) two-equation turbulence model.… Show more
