Recent and Current Projects 

 

aerodynamics 3


Recent projects include:

  • Measuring and modelling underbody flow velocity and pressure measurements for track systems for high speed railways. Track Systems for High Speed Railways: Getting it Right is a collaboration with the University of Southampton, HS1, HS2, Arup and AECOM
  • Measurement of train aerodynamic phenomena in operational conditions including measuring cross-wind forces, train-passing pressures and pressure transients in a variety of tunnels
  • The Aerodynamics of close running ground vehicles [link to http://gow.epsrc.ac.uk/NGBOViewGrant.aspx?GrantRef=EP/N004213/] to investigate the aerodynamics of platooning vehicles
  • Operation of trains through flood water to determine water surface displacement due to aerodynamic effects and splashing mechanisms caused by the wheels
  • Aerodynamics of freight trains and the slipstreams produced. With ever-increasing passenger train speeds in an already overcrowded network, together with environmental and economic reasons, there is a real push to increase freight train speeds. However, the shape and loading of freight trains causes large deformations in the air which can lead to slipstreams severe enough to displace people or cause movement in platform objects
  • Effect of crosswinds on freight slipstream to predict possible consequences to people and objects nearby.
  • Measurement of slipstreams for overheard electrification; trackside structures; meteorological monitoring; platform safety.
  • Aerodynamic measurements for HS2, focussing on passing pressures and the effect of tunnel hood shapes on the emission of audible micro-pressure waves.
  • AeroTRAIN project: to investigate aerodynamic effects of vehicles, in order to ease rail vehicle certification processes in Europe and to promote interoperable rail traffic across the region. The BCRRE involvement included crosswind measurements, measurement of tunnel pressure transients and slip stream effects.
  • LifTRAIN project: The overall aim of this research project is to provide and improve understanding of the flow around train bodies and their reactions to cross winds.
