Abstract The aerodynamic resistance of a train running in the open air limits the maximum
speed that can be attained by the train. For this reason, evacuated tube trains (ETT) are being
considered as valid alternatives to be implemented in the future. The atmosphere in the tube,
the so-called blocking ratio and the length of the streamlined nose are the key factors affecting
the aerodynamic performances of these trains. In the present work, we investigate evacuated
tube trains with different lengths of the streamline nose on the basis of computational fluid
dynamics (CFD). The three-dimensional steady compressible Navier-Stokes equations are
solved.… More >
