Analytical results for soot concentration, average particle size, and of the size distribution are obtained for a free radical soot growth model which includes a constant nucleation source, growth, and coagulation. Results are obtained with and without coagulation included and for a size independent growth rate as well as growth rate proportional to the surface area. Neither this model nor a nucleation pulse model is able to account for all the results on soot formation for shock tube and pyrolysis experiments.
