The aim of this work is to explore possible alternative explanations for the remarkably low fractal dimensions reported for soot particles by Chakrabarty et al. [Phys. Rev. Lett., 102(23):235504, 2009]. A stochastic population balance model has been developed and applied to simulate the formation of soot particles in a premixed laminar sooting flame. The model involves inception, coagulation, surface growth and condensation processes. The fractal dimension has been calculated using a double logarithmic plot of the number of primary particles against the radius of gyration and √(LW) where L is the length and W the width of the projected particle. The limits of this technique are discussed by comparing fractal dimensions calculated for simulated particles.
