Effects of the length and acceleration of the train on the generated pressure waves in the tunnels

In this research by a numerical approach and using the dynamic mesh technique, train movement from the stop position in one station to the next stop position in the next station along the connecting tunnel is simulated. For this aim, the unsteady forms of continuity and Navire-Stokes equations were solved and the flowfield around the train in different time steps were obtained.
