Prediction of low-speed aerodynamic load and aeroacoustic noise around simplified panhead section model

This paper deals with a low-speed aerodynamic and aeroacoustic analysis of the two-dimensional panhead section model that is a simplification of the pantograph used in high-speed railway (HSR). As a preliminary study of HSR whose actual operating speed is over 300 km/h, the present study considers the low-speed aerodynamics and...
