STUDY ON THE AERODYNAMICS OF FREIGHT TRAINS USED IN CONTAINER TRANSPORT

Sorin ARSENE, Marius-Adrian SPIROIU

Abstract


The paper aims to study the aerodynamic phenomena generated in the case of freight trains. Their study is carried out by the numerical method of simulation with a Computational Fluid Dynamics - CFD type analysis. For this process, it starts from the basic elements that correspond to the 3D geometric modeling of the elements that make up a freight train that is used in Romania (vehicles and track). The type of freight wagons studied is the one generated by platform vehicles, which are used in the transport of containers. The final proposed goal is to identify how the variation in forward resistance (from an aerodynamic point of view) is influenced by the layout of the load on a freight train used in the transport of containers.
