Abstract:

Along with the development of urban Metro works, the Metro station environment and Metro fires attract great attention of the researchers. Building good Metro environment not only means to provide a safe and comfortable travel environment, but also means to reduce the energy consumption, construction cost and operation cost. CFD software is now widely used in the optimization of the environmental control design of Metro works.  4 types of CFD software that are widely used in the design of the environmental control systems of Metro works are presented, the stateoftheart of the researches on the CFD software is described, the existing problems are pointed out and proper recommendations are made.
