Aerodynamic behaviour investigation of the new EMUV250 train to cross wind
چکیده انگلیسی

In this work a numerical-experimental procedure for the aerodynamic optimisation of the new train AnsaldoBreda EMUV250 in terms of behaviour to cross wind, will be presented. The first step of the research consists in evaluating the aerodynamic forces acting on the original geometry of the train by means of wind tunnel tests on scale model and of CFD numerical simulations. Thanks to the information provided by the CFD analysis (pressure distribution, velocity field, etc.), two different new versions of the train, specifically designed to achieve a better cross wind behaviour through a modification of both the train roof and the nose, have been tested in the Politecnico di Milano Wind Tunnel. A final comparison between the three versions of the train considered in this work is presented in terms of force/moment aerodynamic coefficients.
