Smoke-Control Ventilation Modes in an Underground Station in Korea

This study is conducted to determine the optimum smoke-control ventilation mode in underground stations in Korea. Numerical analysis is performed for the underground platform where the fire train is stopped. Three smoke-control modes are considered. Distributions of temperature, smoke and visible range on the platform are analyzed for different smoke different smoke-control modes. The flow characteristics of smoke and heat on the platform of the underground station are also studied numerically.
