Abstract Research purposes ： Subway station is crowded and smaller underground space with the outside world . It is necessary to set up air - conditioning system to control the air environment even in the fire. Therefore, it should be to get the specific detail of subway station, such as air temperature, speed and direction of movement of the distribution, etc.
Research conclusions ： Simulation analysis subway station on the air by subway station internal air environment simulation analysis software TSDI -SCFD1.0 is based on the CFD software. It can be able to realize the simulation analysis carrying out 3 - D on subway station internal air condition. It is successful to use CFD technology in the subway designs by research and development of TSDI - SCFD1.0. It is made up limitation and shortage that of the previous the subway software. The visible image and detailed analysis data can provide the basis for the subway environment designers.
