Application of the Standard Aeronautical CFD Method FLOWer to ETR500 Tunnel Entry

The time-accurate 3D Euler/Navier-Stokes code FLOWer of DLR is applied to a symmetric and a non-symmetric train entering a tunnel test case. The computed pressure signals are compared with full scale measurements of an ETR500 high speed train entering the north portal of the Terranuova Le Ville Tunnel. It is shown that FLOWer is able to compute tunnel entry configurations qualitatively correct.
