Smoke affects fire detection and visibility as well as the number of fire victims through inhalation. The size distributions of smoke particles are prerequisites for understanding the characteristics of fire smoke. The purpose of this work is to find the characteristics for the development of the size distribution of smoke particles in a compartment fire. In this work, the dynamic equation for the discrete-size spectrum of particles was solved using the nodal method. The collision frequency function for the entire regime, reflecting the fractal dimension of the particles, was applied. The results were presented for each variation of the parameters such as the history of the heat release rate, smoke yield, and the size of primary particles. (C) 2011 Elsevier Ltd.
