Study on the Burning Performance of Wood Cribs During Pressure Relief Process of Closed Pressurized Oxygen-supplement Compartments
In order to investigate the impact of the depressurization time of the pressurized oxygen-supplement compart-ments for pedestrian evacuation,this study verified the theoretical relationship between pressure and time during cabin depressur-ization.Depressurization tests were conducted with pressurized oxygen-supplement compartments.From the comparison depres-surization curves from experiments and simulation,it confirmed that the depressurization theory is capable to calculate the depres-surization process of the pressurized oxygen supplement compartments.Furthermore,the pressure relief process of pressurized ox-ygen chamber at high altitude was simulated.The results showed that the use of 1 DN20,2 DN40,and 1 DN65 pressure relief valves can meet the requirements of safe evacuation of such buildings.In the case that the fuel like the 4-layer wooden in the experiment burns in a room with an open door in a closed compartment,there will be small influence on the pedestrian evacuation in the public areas outside the room,if the whole compartment can release pressure in a timely manner.The results of this study can provide reference for the application of high-altitude enclosed pressurized buildings.
