Abstract
The calculation of the mean smoke layer temperature is not sufficient to identify the hazardous conditions in case of a confined fire. The knowledge of the vertical temperature gradient is necessary, mainly in high compartments.
A new method is presented to calculate the vertical temperature distribution in the smoke layer using the discretized conservation equations.
It is shown that, when the smoke layer thickness increases, the mean temperature increases, and the difference between the mean layer temperature and the temperature near the ceiling increases. The results are compared with the previously published measurement. We conclude that the model gives an acceptable temperature prediction far from the ceiling.
