Numerical and Experimental Investigation on Smoke-Buffer Effect of Different Smoke-Control Combination in Corridor
In this paper, full-scale experiments had been designed and implemented in wind tunnel to simulate the corridor fire. A combination model with smoke buffer and other smoke-control modes was established on the base of experiment, and Fire Dynamic Simulation (FDS) was applied to simulate fire in the same conditions. The results reflected that the model is reasonable and viable by compared the simulation results and the experiment dates and the error of the average temperature is about 4.08%. Experimental studies also show that in those modes one smoke outlet is needed every 30m and it is better to set near the ignition source. Its exhaust efficiency is 72.1%, better than others; additionally it needs to put up smoke screen to strengthen the smoke exhaust effect. Thus the best combination with smoke-control is perfect in corridor.
