Large eddy simulation of smoke movement in a teaching building

Smoke movement during fire in a large teaching building without sprinkler was simulated by large eddy simulation (LES) model. Several fire scenarios were considered to show the smoke movement in vertical and horizontal direction. It is found that the lower storey the fire location is, the more dangerous the people inside are for a multi-storey building. Also we can find when the smoke spreads along the corridor and encounters an atrium, it will accumulate largely in the atrium. In addition, the reasonable application of fire shutter was discussed. Simulated results show that simultaneous releasing the fire shutters of the fire storey and above can efficiently control smoke to spread horizontally.
