| description | Smoke layer interface height is an important parameter in fire safety science. In this paper, two methods are proposed on the basis of integral ratio method and the least squares method. a series of experiments were conducted in a 1:10 scale model tunnel for determining the smoke layer interface height in tunnel fire. The interface height of the smoke layer determined by the new methods have been compared with other existing approaches, including integral ratio method, least squares method, N-percentage rule. The comparison results show that the results of the least squares method based on the transition layer can be relatively reasonable and agree well with the visual observations for all experimental condition. In addition, the usage scenarios and considerations of the N-percentage rule were also discussed. |
