Abstract

Models of different degrees of complexity describing diffusion and reaction in a stagnant boundary layer surrounding a carbon particle are constructed. The models include the heterogeneous combustion reactions with the intraparticle effects lumped at the particle surface in concert with radiation resulting in nonlinear boundary conditions. The genesis of steady-state structures associated with carbon combustion is identified. The sensitivity of the steady-state structures to the complexity of the model for diffusion and reaction in the boundary layer and to the choice of values for some key parameters appearing in the model is investigated. The qualitative features of the steady-state structures are sensitive only to the environment with which the particle is in radiant interaction and the O. content in the gas phase.
