Study on Fire Plume in Large Spaces Using Ground Heating

As a new technology of enclosure heating developed rapidly in recent years, the grounding heating has been applied more and more extensively in the world. The movement of fire plume in large spaces using ground heating has some special characteristics, which have significant effects on the detection of early fire, evacuation and so on. In this paper, the particular movement of smoke in large spaces using grounding heating is theoretically analyzed by the Morton's integral equation. The smoke movement in a large enclosure space with 20 × 12 × 20m (high), which is with and without the ground heating separately, is simulated and comparatively studied.
