A full-scale real train experiment was conducted to validate the suitability and effectiveness of the numerical method for the simulation of the flow field around the train and the tunnel in the present work. A CRH2 train shown in Fig. 5(a), the same model as the high-speed train used in this simulation, was used as the trial train. This train contains 8 cars, including a head car, a tail car and 6 middle cars. The total length of the train is 201.4 m. The tested train was run at four speeds of

A simulation of the turbine driven by a high-speed train-induced wind in the tunnel was performed using the IDDES method with the SST k-w turbulence model. A full-scale real train experiment was conducted, and the results from a previously published study were employed to verify the computational method and mesh used for the simulation of the flow fields around the train and the turbine. The results show that the differences between the experiment and simulation results are very small. Next, certain variations of the torque of the turbine, the vorticity, velocity, pressure and specific dissipa...
