- Abstract
- In this study, numerical analysis was conducted to evaluate the effect of a fire outbreak at a subway station. For this, velocity at various points of a platform and flow rate at over/under platform extracts and air-vents were measured. These were used to estimate velocity field numerically and the reliability of numerical analysis findings obtained through the comparison of the estimated values and measured values could be enhanced. And, numerical analysis of heat and smoke behavior under 2 different exhaust capacities in case of a fire at a platform was carried out and characteristics of heat, smoke, visibility and various gases were analyzed and compared.
