Boundary conditions for the transit of a train through a tunnel with special reference to the entry and exit mesh fractions and the contact surface (TM-AERO-066)

Unsteady flow in railway tunnels has been the subject of a considerable number of experimental and theoretical investigations. Most of the methods of calculation use a mesh method to solve the unsteady flow characteristic equations and a number of these have been discussed at previous International Symposia on the Aerodynamics...
