The two-dimensional, unsteady, laminar conservation equations for mass, momentum, energy, and gas-phase species transport are solved numerically in spherical coordinates. The particle mass, momentum, and energy equations are also solved simultaneously with the gas-phase equations in order to study the effects of particle entrainment on heat and mass transfer, and combustion around a single spherical carbon particle. The numerical solution for the case of single particle combustion gives the particle temperature and diameter variation as well as the gas-phase velocity, temperature and species concentrations as a function of time. The results with particle entrainment are compared with those without particle entrainment and in a quiescent environment. The effects of particle size, preexponential factor, initial relative velocity, and free-stream oxygen concentration on the combustion of a single particle are also explored.
