High-speed train

AERODYNAMICS

CAF conducts aerodynamic studies during the development phase of each project, in order to ensure the correct performance of the vehicles and compliance with applicable standards and regulations.

During the design phase, CAF uses aerodynamic simulations, using the very latest software tools available on the market. The CFD (Computational Fluid Dynamics) calculation is directed at guaranteeing the correct and safe performance of the train, with regard to the following characteristics:

  • Side winds
  • Wake effects
  • Pressure effects in the open field
  • Pressure effects in tunnels
  • Ballast projections

ENERGY EFFICIENCY

Likewise, in order to optimise the energy efficiency of vehicles, CAF is conducting studies to improve thermal comfort and train drag.

The calculations are accompanied by the corresponding tests in the validation phase, on a test bench (wind tunnel, installations with mobile models, etc.) and also on the track.

As part of its objective to achieve technological excellence in different areas, CAF is participating in a number of research projects within the sphere of rail aerodynamics. As a result of the experience acquired, CAF is providing an AENOR representative to the CEN TC256 WG6 aerodynamic standardisation group.
