Abstract
The goal of this study is to develop a simple model for predicting convective heat transfer in compartment fires. Asthe first step of this study, experiments using a small scale compartment have been conducted. The method for estimating the mass flow rate through opening using air temperature in compartment in case of uni-direction flow was considered. The rate of convective heat transfer is obtained by subtracting heat transfer rate through the opening of compartment from the heat release rate of fire source. Therefore, the convective heat transfer coefficient can be calculated from temperature difference between hot gas and wall surface and surface area of compartment. As a result of experiments and analysis, this method seems to be convenient. The convective heat transfer coefficient are found to be 0.018-0.040 kW/m^2/K and 0.007-0.013 kW/m^2/K before and after the fire is extinguished, respectively.
