The goal of this study is to develop a simple and practical model for predicting an overall convective heat transfer coefficient in compartment fires. Experiments using a small scale (500mm cube) and a medium scale (1500mm cube) compartments were conducted to investigate the convective heat transfer coefficient in the early stage of fires. It is found that dimensionless heat release rate Q^* which is defined using heat release rate of fire source and height of compartment as characteristic length can provide a fair scaling parameter for convective heat transfer coefficient with different heat release rate and scale of compartment in the early stage of fire in which the flow induced by fire source is considered to be dominant.
