This report documents the library of thermodynamic data used with the NASA Glenn computer program CEA (Chemical Equilibrium with Applications). This library, containing data for over 2000 solid, liquid, and gaseous chemical species for temperatures ranging from 200 to 20,000 K, is available for use with other computer codes as well. The data are expressed as least-squares coefficients to a seven-term functional form for C((sup o)(sub p)) (T) / R with integration constants for H (sup o) (T) / RT and S(sup o) (T) / R. The NASA Glenn computer program PAC (Properties and Coefficients) was used to calculate thermodynamic functions and to generate the least-squares coefficients. PAC input was taken from a variety of sources. A complete listing of the database is given along with a summary of thermodynamic properties at 0 and 298.15 K.

Since the publication of the Second Edition in 2001, there have been considerable advances and developments in the field of internal combustion engines. These include the increased importance of biofuels, new internal combustion processes, more stringent emissions requirements and characterization, and more detailed engine performance modeling, instrumentation, and control. There have also been changes in the instructional methodologies used in the applied thermal sciences that require inclusion in a new edition. These methodologies suggest that an increased focus on applications, examples, problem-based learning, and computation will have a positive effect on learning of the material, both at the novice student, and practicing engineer level. This Third Edition mirrors its predecessor with additional tables, illustrations, photographs, examples, and problems/solutions. All of the software is ‘open source’, so that readers can see how the computations are performed. In addition to additional java applets, there is companion Matlab code, which has become a default computational tool in most mechanical engineering programs.

The new edition of a classic textbook on combustion principles and processes, covering the latest developments in fuels and applications in a student-friendly format Principles of Combustion provides clear and authoritative coverage of chemically reacting flow systems. Detailed and accessible chapters cover key combustion topics such as chemical kinetics, reaction mechanisms, laminar flames, droplet evaporation and burning, and turbulent reacting flows. Numerous figures, end-of-chapter problems, extensive reference materials, and examples of specific combustion applications are integrated throughout the text. Newly revised and expanded, Principles of Combustion makes it easier for students to absorb and master each concept covered by presenting content through smaller, bite-sized chapters. Two entirely new chapters on turbulent reacting flows and solid fuel combustion are accompanied by additional coverage of low carbon fuels such as hydrogen, natural gas, and renewable fuels. This new edition contains a wealth of new homework problems, new application examples, up-to-date references, and access to a new companion website with MATLAB files that students can use to run different combustion cases. Fully updated to meet the needs of today’s students and instructors, Principles of Combustion: Provides problem-solving techniques that draw from thermodynamics, fluid mechanics, and chemistry Addresses contemporary topics such as zero carbon combustion, turbulent combustion, and sustainable fuels Discusses the role of combustion emissions in climate change and the need for reducing reliance on carbon-based fossil fuels Covers a wide range of combustion application areas, including internal combustion engines, industrial heating, and materials processing Containing both introductory and advanced material on various combustion topics, Principles of Combustion, Third Edition, is an essential textbook for upper-level undergraduate and graduate courses on combustion, combustion theory, and combustion processes. It is also a valuable reference for combustion engineers and scientists wanting to better understand a particular combustion problem.

One method to access unconventional, heavy-oil and natural bitumen resources as well as waterflood residual oil is to apply in situ combustion (ISC) to oxidize in place a small fraction of the hydrocarbon thereby providing heat to reduce oil viscosity and pressure that enhances recovery. ISC is also attractive because it provides the opportunity to upgrade oil in-situ by increasing the API gravity and decreasing, for instance, sulfur content. Experimental analysis of crude-oil oxidation kinetics provides parameters, such as activation energy, for modeling and optimization of ISC processes. The complex nature of petroleum as a multi-component mixture and multi-step character of oxidation reactions complicates substantially the kinetic analysis of crude-oil. Isoconversional techniques provide model-free methods for estimating activation energy and naturally deconvolve multi-step reactions. In addition, isoconversional methods are also useful as a screening tool to recognize the burning characteristics of different oils. By using experimentally determined combustion kinetics of different oil samples along with combustion tube results, we show that isoconversional analysis of ramped temperature oxidation data is useful to predict combustion-front propagation. It also provides new insight into the nature of the reactions occurring during ISC. Ramped temperature oxidation (RTO) tests with effluent gas analysis are conducted to probe ISC reaction kinetics along with isothermal coke formation experiments. The role of oxygen during coke formation reactions (i.e., fuel formation for ISC) is investigated using X-ray photoelectron spectroscopy (XPS) of intermediate reaction products. The XPS data is analyzed along with companion RTO experiments to obtain a simplified multi-step reaction scheme. Synthetic cases illustrate the connection between a proposed reaction scheme for oil/matrix pairs and one-dimensional combustion front propagation. Analysis of experimental results illustrate that the reaction scheme is capable of reproducing experimental results including the basic trends in oxygen consumption and carbon oxides production for RTO experiments as a function of heating rate for both good and poor ISC candidates. The combination of XPS and RTO studies indicates that the quality (or reactivity) of coke formed during the process is a function of oxygen presence/absence.
