碩士 === 國立交通大學 === 機械工程系所 === 103 === In the past, many cases and researchers use FDS(Fire Dynamics Simulator) to investigate the relationship between fire and plume, so that the building characteristics can keep people survival inside without more prevention equipment. But many of fire simulations didn’t involve the materials which were burned by the main fire. It is because the technical difficulties to precisely understand the material properties. In recently years, the newer research equipment invention, the more related study made about different materials properties. This study investigates the effects of the different burning materials in a room which contain three main furniture(Sofas, Wood Table and Television) made by PU Foam, White Pine and PVC. The room is pretended that much paper in a trash can ignites causing a fire. The fire position on the path exactly between sofa and wood table, therefore leading the fire spreading. Main simulation results show that PU Foam material need a high temperature about 600 degree to be ignited and the spreading characteristic is the worst in this three. PVC just need the lower temperature about 340 degree to ignite by thermal radiation. White pine stared to burn at 350 degree and the higher temperature and the better burning rate.
