Analysis ofFlow Characteristics around H igh-Speed Railway Bridge-Vehicle System under CrossW ind

  • Publish Date: 25 Oct 2005
  • An analysis was carried out for flow characteristics around a vehicle-bridge system consisting ofGerman ICE ( intercity-express) vehicle and standard simply-supported bridge under cross wind. Based on the two-dimensionalReynolds averaged incompressible Navier-Stokes equations, the RNG (renormalization group) turbulencemodelwas used in the numerical simulation. Triangulargrid and quadrilateral grid were used to divide the computational domain, the finite volume method was adopted to discretize the governing differential equations, and the pressure-velocity field was coupled using the SIMPLE (semi-implicitmethod for pressure-linked equations) algorithm. Furthermore, the research results of driven cavity flowswere applied to the analysis of flow characteristics around the vehicle-bridge system considering the wind-break wall effec.t The analysis shows that the wind-break wall of a high-speed railway bridge has the similar vortex characteristics of driven cavity flows in preventingwind.
