摘要：In order to study the influences of natural gas pipeline pressure on jet fire with FDS(fire dynamics simulation) software, based on principle of fluid mechanics and Thornton flame model, characteristics and hazard scope of the jet fire were comparatively studied for different pipe pressure. The results show that characteristics and hazard scope of the jet fire are largely affected by different pressure. When the pipe pressure is 0.2MPa and 0.4MPa, the size of both leak holes are same, during a same period, the latter flow is greater than the former. When the pipe pressure is greater than 0.8MPa, the leakage hole size is 100mm, and the maximum temperature, diameter and the high temperature affected area of the flame are increased.
