چکیده انگلیسی
Aiming at the “cabin” fire safety design concept in large space buildings, and combined with a real cabin with a spray system, Large Eddy Simulation was used for simulating the flow state of cabin fire smoke under sprinkler spray. The effect of sprinkler spray on overflowing smoke layer and the characteristics of overflowing smoke under sprinkler spray were analyzed and discussed. Results showed that sprinkler spray had a good cooling effect on smoke layer, but it made smoke layer unstable at the same time, leading to the smoke congestion phenomenon. As a result, smoke spillage was added, and the characteristics of overflowing smoke were significantly changed.
