Aerodynamics of Freight Trains: An Open Database of Geometries for CFD Analyses

The computational investigation of freight train aerodynamics requires the production of a surface geometry of the vehicle in order to run the simulation. To address the need for efficient production of these geometries that comes with the growing employment of numerical studies in this field, a database of representative wagon and locomotive geometries is proposed in this work. After the database is introduced, a demonstrational computational fluid dynamics study is presented, considering the geometry of a single flat wagon with a container for two different levels of detail, and the results of the simulations are compared and discussed.
