Throughout its previous four editions, Combustion has made a very complex subject both enjoyable and understandable to its student readers and a pleasure for instructors to teach. With its clearly articulated physical and chemical processes of flame combustion and smooth, logical transitions to engineering applications, this new edition continues that tradition. Greatly expanded end-of-chapter problem sets and new areas of combustion engineering applications make it even easier for students to grasp the significance of combustion to a wide range of engineering practice, from transportation to energy generation to environmental impacts.Combustion engineering is the study of rapid energy and mass transfer usually through the common physical phenomena of flame oxidation. It covers the physics and chemistry of this process and the engineering applications-including power generation in internal combustion automobile engines and gas turbine engines. Renewed concerns about energy efficiency and fuel costs, along with continued concerns over toxic and particulate emissions, make this a crucial area of engineering.New chapter on new combustion concepts and technologies, including discussion on nanotechnology as related to combustion, as well as microgravity combustion, microcombustion, and catalytic combustion-all interrelated and discussed by considering scaling issues (e.g., length and time scales)New information on sensitivity analysis of reaction mechanisms and generation and application of reduced mechanismsExpanded coverage of turbulent reactive flows to better illustrate real-world applicationsImportant new sections on stabilization of diffusion flames-for the first time, the concept of triple flames will be introduced and discussed in the context of diffusion flame stabilization

The accurate prediction of combustion processes inturbulent reacting flows is essential for the design ofadvanced combustion technologies. Numerical simulation techniques becomeviable tools to address such design challenges if adequate modelsare available. In this work, computational models are developed forapplication to large-eddy simulation (LES). In particular, threecritical modeling aspects are considered, namely local flame extinctionand reignition, nitrogen oxide formation, and noise-generation bycombustion. These models are integrated into theflamelet/progress variable formulation, thus allowing for a consistent treatmentof different combustion-physical effects in a unified framework. The computational models are analyzed in a priori studiesand applied to LES for different flame configurations, includingturbulent jet flames and a realistic aircraft engine combustor. All LESmodels are validated using experimental data, and the underlyingphysical phenomena are discussed in great detail.

Effects of Gas Generation on Nano-Al Fueled Ene...
50,40 € *
ggf. zzgl. Versand

The reactions of two nano-thermites, aluminum (Al)with copper oxide (CuO) and Al with nickel oxide(NiO) are studied. These oxidizers were selectedbased on their predicted properties: similar flametemperatures but significantly opposing gasgeneration. Thermal equilibrium calculations predictthat Al+CuO will have a high gas output and theAl+NiO will produce little gas. Flame propagationrates and peak pressure measurements were taken forboth composites at various equivalence ratios usingan instrumented flame tube. Results show that theAl+CuO had approximately twice the propagation rateand peak pressure of the Al+NiO. A DSC/TGA was usedto determine the properties of the composites andreactants under low heating rates. Results indicatethat under slow heating both composites experiencealmost no mass loss. The results suggest that themelt-dispersion mechanism, which is only engaged athigh heating rates, leads to a dispersion of highvelocity molten Al clusters that promotes a pressurebuild-up by inducing a bulk movement of fluid. Thismechanism may promote convection without the need foradditional gas generation.

Coal Pyrolysis and Char Combustion Under Oxy-Fu...
48,79 € *
ggf. zzgl. Versand

Carbon dioxide emissions will continue to be a major environmental concern due to the fact that coal will remain a major fossil-fuel energy resource during the next few decades. Various CO2 capture and storage strategies have been considered for coal-fired power-generation plants to mitigate CO2 emissions. These technologies include pre-combustion or fuel decarbonisation, post-combustion, and oxy-fuel technology. In oxy-fuel combustion, fuel is combusted in oxygen rather than air and the oxygen stream is usually diluted by recycled flue gas to control the flame temperature and ensure a proper heat transfer without major changes in the layout of the boiler. In this thesis, oxy-fuel combustion technology is investigated to evaluate the effect of the O2/CO2 environment on coal combustion.

This volume describes fire behavior and fire protection of timbers in outdoors and indoors application mainly in construction industry. The Authors' novel approach considers the relationship between various species and age of timbers and its fire behavior at different thermal and fire loads. Quantitative data of ignition speed and flame propagation as well as generation of heat, smoke and toxic products are discussed. Analysis of fire resistance of various types of building materials based on timber of different species as well as the novel data on the effect of natural and accelerated aging of timbers on its fire behavior are discussed. The main practical methods of fire protection of new and ancient timber buildings and structures to increase its fire resistance are considered. The book should be useful for a wide range of readers: chemists, physicists, material scientists, architects, engineers, constructors and restorers.
