A stochastic model of a turbulent diffusion flame in a confined space has been developed by assuming that each fluid particle behaves as an ideal batch in which a chemical equilibrium holds at any instant, and that the particle undergoes random binary collision and redispersion immediately to produce two equal particles having the average thermodynamic state. This model may afford not only the descriptions of macroscopic quantities such as pressure and average temperature but also those of nonuniformities in composition and temperature. Results of computation performed for constant-volume cases suggest that the model characterizes the main part of diesel combustion in which initial segregation of fuel and air is disintegrated from time to time reaching a final uniform state, by forming flames of a highly turbulent nature. Some considerations are made regarding the mixing rate parameter that determines overall rate of the process.
