CFD Analysis on Fire Feature of Subway Station with Different Location of Ticket Machine

摘要

Rational spatial distribution plays a significant role on fire safety of subway station. The location of ticket machine is one of the main factors affecting fire feature of such stations. Taking a certain subway station as a physical model, this paper carries out simulation analysis on several fire scenarios with the help of software FDS. By comparing the fire temperature, smoke density as well as visibility under different kinds of space between ticket machine and the escape exit, the appropriate space between ticket machine and escape exit is obtained which could be a reference for practical projects.
