摘要

Aiming at the problem of vent area designing of all flooded high expansion foam system, using Voronoi random model assumption, it analyzed that the minimum rate of foam supply and space of fire source were the two important factors when design the vent area under the specification of the minimum value vent velocity as 5m/s. Therefore, on basic assumptions of the random coefficient, relative density , fluid form, heat release rate and the evaporation of the broken foam, it used fluent software to simulate the vent area of the high expansion foam system designed for a hangar. The result is that when the vent area is a constant, the minimum rate of foam supply is higher, the area will reach to the theoretical value closer, and the fire power is also a great influence on the foam flooded time of per height. The flooded rate will increase firstly, then decrease, and finally be stable. If the minimum rate of foam supply is 400m~3/s and the fire power is 3MW in a hangar, the vent area can be reduced about 12% compared with the theoretical value.
