Abstract :
Air quality does much to people´s health. Based on measured air flow rates, effects of different ventilation and extraction conditions, including velocity, temperature of ceiling ventilation, longitudinal ventilation and extraction on air quality at subway station platform are simulated by CFD, then strategies to optimize this air quality can be (1) decrease ventilation temperature, (2) increase ventilation velocity, (3) activate both ventilation and extraction, etc. All of these will serve as guidelines for good air quality in subway design and performance.
