Summary
With the increase of train's running speed, train aerodynamics have been attracted significantly attention in recent years. The flow around trains could be a threat to the running safety and riding comfort of trains. How to minimize the aerodynamic effect on a train is a key factor for the design of a high-speed train. The content of the train aerodynamics mainly includes the aerodynamic forces and flow field of trains in the open air, crosswind stability, trains passing events, trains passing through a tunnel and passing each other in a tunnel, aerodynamic optimization on the train shape, aerodynamic noise, snow accumulation, and so on. The flow around trains mentioned above could be studied by means of either experiments or Computational Fluid Dynamics. This special issue will focus on the study on the train aerodynamics and related topics, especially the new tools, developments and study on the aerodynamic issues of the high-speed train in China.
