Wind Tunnel Analysis of the Aerodynamic Loads on Rolling Stock over Railway Embankments: The Effect of Shelter Windbreaks

الملخص EN

Wind-flow pattern over embankments involves an overexposure of the rolling stock travelling on them to wind loads.

Windbreaks are a common solution for changing the flow characteristic in order to decrease unwanted effects induced by the presence of cross-wind.

The shelter effectiveness of a set of windbreaks placed over a railway twin-track embankment is experimentally analysed.

A set of two-dimensional wind tunnel tests are undertaken and results corresponding to pressure tap measurements over a section of a typical high-speed train are herein presented.

The results indicate that even small-height windbreaks provide sheltering effects to the vehicles.

Also, eaves located at the windbreak tips seem to improve their sheltering effect.
