摘要：
A particle stochastic trajectory model for turbulence-particle reaction interactions is proposed and formulated in the present paper. This model provides the basis for a comprehensive model of pulverized coal combustion. It is applied to the simulation of gas-particle turbulent flow and combustion in a pulverized coal-fired swirl combustor. The results are compared with the measured test data and those obtained by the particle stochastic trajectory model without considering turbulence-particle reaction interactions. The predicted gas temperature and species concentrations in the upstream region of the combustor are improved by utilizing the model with turbulence-particle reaction interactions.
