Studies of Smoke Filling Process in Large Spaces

Analysis was made for smoke filling process in large space building,and some full scale pool fire tests for comparison were made in USTC large space experimental hall.The results showed that the temperature rise of smoke layer was very low,but the descending of smoke layer was quick.The zone model could still be used to simulate the smoke movement in large spaces.For the pool fire,the calculation model should be selected based on the heat release rate.
