Natural-convection turbulent diffusion propane flames 
in air have been modeled numerically. The statistical method (Monte 
Carlo method) has been used for calculation of thermal-radiation transfer. 
In modeling the emission of radiation, we allowed for turbulent fluctuations 
of temperature. The data obtained have been compared to the results 
of measurements of the concentrations of the main components (fuel, 
oxygen, and carbon dioxide and monoxide), mean temperature and velocity 
and their turbulent fluctuations, the profiles of the emitted heat 
fluxes, and the total amount of emitted energy.
