摘要：
Natural fire is associated with the diffusion flame. The height of the buoyant diffusion flame is important for calculations of heat transferred to distant objects, secondary fuel, and also for fire detection and suppression system. The heat radiated toward the floor of the compartment is expected mainly from the flame itself. Flame touching the ceiling is construed as onset of flashover. There are a number of correlations available in the literature for estimating the flame heights for open fires or free burn fires. In the present article, an experimental study has been carried out for determining the flame height in a compartment as well as in the open. The predictions of these correlations are compared with the experimental data to find out the best fit correlation. It is also found that the correlation for calculating flame heights in free burn conditions can be applied successfully for predicting flame heights in the compartment fires. © 2007, Baywood Publishing Co., Inc.
