지하철 객차 축소모형 화재실험

초록

Fire spread in a subway saloon is investigated using a 1/10 reduced scale model. The dimension of the reduced model saloon is 1.9 m long, 0.290 m high and 0.235 m wide. Only one- sided four doors of the subway passenger coach are opened. The n-heptane pool fire with heat release rate 2.33 kW is used as a fire source and Froude number scaling law is adopted. In this scaling law we cannot suitable reappear combustibility of materials in a reduced model so we don’t use the very materials of the coach. The temperature, heat release rate and mass loss rate are measured to analyze fire development in the coach. The fire spread of the Coach in this test is mainly controlled by ventilation through opened doors.
