dc.description.abstracttranslated | As the train moves creates turbulence which is associated with high air velocities and rapidly changing pressure fields. This works seeks to explain the flow field properties of a freight train locomotive. A Reynolds-Averaged Navier Stokes (RANS) model, based on the k-ω turbulence model, is used to simulate the locomotive aerodynamic performance. The aerodynamic behavior of a
locomotive moving with crosswinds, with and without a windbreak is also studied. The flow structure, velocity, pressure, pressure coefficient, turbulent kinetic energy k, specific dissipation factor ω, and the effect of the windbreak wall on the flow around the locomotive is defined using OpenFoam code. | el |
