Transient Numerical of Piston Wind in Subway Station

Abstract:

Computational Fluid Dynamics (CFD) is used for the investigation of the piston wind. The Navier-Stokes (N-S) equations and standard turbulence model were applied to set up the model. The train transient aerodynamic characteristic has been research during the crossing process. The simulation results are trustworthy and numerical simulation of piston wind is feasible using dynamic grid in CFD software, which provides the basis for the virtual design of piston wind. It is significant importance for further studying the structure of train, shorten its development and guiding significance for practical application.
