Abstract
This study focuses on computational analysis for the improvement of the tunnel ventilation and the environmental control system of the subway by solving Reynold-averaged Navier-Stokes equations for train-induced unsteady flow. The two-equation turbulence model can predict velocity and pressure field at the tunnel. The sharp interface method is used for the moving boundary of an immersed solid. The flow rate through the natural ventilation-shaft and the features of the train-wind in the subway tunnel help to find better installation locations for the air-curtain. The air-curtain separates two adjacent environments and reduces the transfers of bacteria and radioactive particles. The ANSYS CFX software is used to perform unsteady computations of the flow field at the subway tunnel. (C) 2011 Elsevier Ltd. All rights reserved.
