Most rocket propellant is inflammable, explosive and poisonous liquid, and the leakage of which endangers the safety of personnel and equipments, and also brings environmental pollution. In this paper, fluent software is used to simulate evaporation and diffusion of N2O4 in a propellant storehouse, and analyze its safety. The results indicate that, in an enclosed space, the concentration of poisonous vapor generated by the leaked N2O4, in the region above the liquid pool(about 1.5 meters from the ground), reaches or exceeds the limit (100ppm) in about 10s~20s, which is seriously harm to human body, but in the region far from the liquid pool (around the storage tank), does not reach the limit, and in the lower region of the room(about 2 meters from the ground), the concentration reaches or exceeds the limit in about 40s~50s. A ventilation mode of exhausting air at the bottom and inhaling air at the top is beneficial to drain the poisonous vapor out. |
