摘要: The present work is devoted to the study of non-premixed turbulent combustion with PDF approach using three turbulence models: k-ɛ model, modified model and RSM model. A detailed kinetic mechanism used in numerical simulations. models are compared evaluated experimental data results literature. evaluation concludes that most appropriate for simulating this kind flame. effect hydrogen addition on methane performed. Hydrogen causes elevation temperature, decreasing CO CO2 mass fractions but leads increase NO fraction.
