STATISTICAL MODELING OF THERMAL-RADIATION TRANSFER IN NATURAL-CONVECTION TURBULENT DIFFUSION FLAMES. 2. FLAME ABOVE A GAS BURNERA. Yu. Snegirev UDC 536.46:614.841.41 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.
