Abstract
Measurements of vents wind velocity of smoke control system in metro station prove it is a universal problem that the long air duct can’t distribute air equally. Therefore, mathematical simulation of fire smoke flow in tunnel has been done under three smoke extract system modes. Results show the temperature in non-uniform smoke exhaust system is the biggest near the fire source; the uniform smoke exhaust system can control smoke movement well. Therefore, it is crucial to make every vent equalvelocity in the long smoke removal pipe.
