Simulation-aided design of environment control system for underground railway Line 5 in Shenzhen

With the Dalang station as object, develops a mathematical and physical model of underground railway station. Simulates the temperature and velocity fields under normal and fire situation based on the defined boundary of deign conditions. As a result, the design temperature and velocity in platform and hall can be maintained under normal condition, the makeup air system of platform can be kept shut under hall fire condition and the tunnel fan needs to be operated under platform fire condition.
