Estimation Method of Cooling Load Caused by Train Wind in an Underground Station

摘要

In this study, the cooling load caused by train wind in an underground station was studied using field measurements and computational fluid dynamics (CFD) simulations. The main conclusions are as follows: (1) The measurement results showed that air volume of the train wind was greatly affected by the train speed and the tunnel configuration such as single or double track. (2) In the CFD simulation, the train was modeled as a moving body to simulate train wind. The CFD simulation with a pressure loss model in the tunnel could reproduce the measured train wind. (3) The influence coefficient of train wind on the platform cooling load was estimated by the CFD simulation.
