Abstrakt

The interaction between burning char/carbon particles of different sizes is analyzed in a quasi-steady approximation. The method of solution is based on the expansion into irreducible multipoles developed in the earlier paper. It is assumed that the chemical reaction which occurs on the surface of particles is of first order. The developed method is applied for the analysis of burning rate of spherical and cylindrical clouds of particles. The obtained results are presented in terms of correction factor defined as a ratio of a burning rate of a particle located inside a cloud to a single particle burning rate. It is showed that the burning rate of a cloud of particles is determined by a combustion rate of a primary (central) particle. The comparison of the theoretical results obtained with the aid of proposed model with experimental data demonstrates the validity of the developed model.
