Turbulent reacting flows
Most chemically reacting flows in various applications such as energy production, piston engines, gas turbines and chemical engineering occur under turbulent flow conditions. Interactions between turbulence and chemical reactions have a major impact on bulk and local reaction rates, flow dynamics, system stability, and pollutant formation, thus, leading to many fascinating phenomena. Investigating and understanding turbulent reacting flows remains a major and worthwhile challenge to experimentalists, modellers and engineers working in research and development. The course aims at summarizing the state-of-the-art knowledge on turbulent reacting flows and discussing advanced models and methods applied to research into such flows. The course focus is placed on premixed turbulent combustion, because, in this case, (i) the influence of chemical reactions on turbulence is particularly strong due to large density variations in flames and (ii) the influence of turbulence on burning rate is particularly strong due to highly non-linear dependence of the rates of major chemical reactions on the temperature, which significantly varies in flames. Turbulent combustion physics will be covered, basic models of various phenomena in turbulent flames will be discussed, an overview of numerical models implemented into the major CFD (Computational Fluid Dynamics) codes will be given, and fundamental issues that still challenge the combustion community will be emphasized.
