It illustrates a new extinction exponent concept, which enriches the combustion theory. Above all, the book provides the following: a) a series of carefully measured data and theoretical analyses to reveal the intrinsic mechanisms of the fuel composition effect on the propagation and extinction of lean syngas/air flames; b) a mixing model and correlation to predict the laminar flame speed of multi-component syngas fuels, intended for engineering computations; c) a new “extinction exponent” concept to describe the critical effects of chemical kinetics on the extinction of lean premixed syngas/air flames; and d) the effects and mechanism of the dilution of incombustible components on lean premixed syngas/air flames and the preferential importance among the thermal, chemical and diffusion effects.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053Fluid mechanicsThermodynamicsHeat engineeringHeat transferMass transferEnergy efficiencyEngineering Fluid Dynamicshttps://scigraph.springernature.com/ontologies/product-market-codes/T15044Engineering Thermodynamics, Heat and Mass Transferhttps://scigraph.springernature.com/ontologies/product-market-codes/T14000Thermodynamicshttps://scigraph.springernature.com/ontologies/product-market-codes/P21050Energy Efficiencyhttps://scigraph.springernature.com/ontologies/product-market-codes/118000Fluid mechanics.Thermodynamics.Heat engineering.Heat transfer.Mass transfer.Energy efficiency.Engineering Fluid Dynamics.Engineering Thermodynamics, Heat and Mass Transfer.Thermodynamics.Energy Efficiency.665.77Zhang Yangauthttp://id.loc.gov/vocabulary/relators/aut1063882MiAaPQMiAaPQMiAaPQBOOK9910299569903321Propagation and Extinction Studies of Laminar Lean Premixed Syngas2535154UNINA
