Abstract
A series of experiments was carried out to grasp flammability of combustible material which was supplied with water droplet on the horizontal surface of specimen. The cone calorimeter was used as experimental apparatus. As for specimen, Plywood, PMMA, Polyurethane foam, Polyethylene foam, n-Heptane were selected. The size of specimen was 100mm wide, 100mm long. Regarding the experimental conditions, the heat flux rate radiated from heater was constant (50kW/m2) and supplied watering was changed. As the result of experiments, on each specimen, heat release rate decreased but total heat release was not changed with increasing water supply rate. Based on the heat balance in combustible material surface, the prediction method of heat release rate per burning area corresponding to heating strength and the rate of water supply was proposed.
