This book was released on 2008 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research program was designed to enhance our understanding of the behavior of fluids and fluid mixtures containing chain-like molecules. The original objective was to explain and predict the experimentally observed thermophysical properties, including phase equilibria and dynamics, of systems containing long flexible molecules ranging in length from alkanes to polymers. Over the years the objectives were expanded to include the treatment of molecules that were not chain-like. Molecular dynamics and Monte Carlo computer simulations were used to investigate how variations in molecular size, shape and architecture influence the types of phase equilibria, thermodynamic properties, structure and surface interactions that are observed experimentally. The molecular insights and theories resulting from this program could eventually serve as the foundation upon which to build correlations of the properties of fluids that are both directly and indirectly related to the Nation's energy resources including: petroleum, natural gas, and polymer solutions, melts, blends, and materials.

This book was released on 2005 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular simulation is an emerging technology for determining the properties of many systems that are of interest to the oil and gas industry, and more generally to the chemical industry. Based on a universally accepted theoretical background, molecular simulation accounts for the precise structure of molecules in evaluating their interactions. Taking advantage of the availability of powerful computers at moderate cost, molecular simulation is now providing reliable predictions in many cases where classical methods (such as equations of state or group contribution methods) have limited prediction capabilities. This is particularly useful for designing processes involving toxic components, extreme pressure conditions, or adsorption selectivity in microporous adsorbents. Molecular simulation moreover provides a detailed understanding of system behaviour. As illustrated by their award from the American Institute of Chemical Engineers for the best overall performance at the Fluid Simulation Challenge 2004, the authors are recognized experts in Monte Carlo simulation techniques, which they use to address equilibrium properties. This book presents these techniques in sufficient detail for readers to understand how simulation works, and describes many applications for industrially relevant problems. The book is primarily dedicated to chemical engineers who are not yet conversant with molecular simulation techniques. In addition, specialists in molecular simulation will be interested in the large scope of applications presented (including fluid properties, fluid phase equilibria, adsorption in zeolites, etc.).Contents: 1. Introduction. 2. Basics of Molecular Simulation. 3. Fluid Phase Equilibria and Fluid Properties. 4. Adsorption. 5. Conclusion and Perspectives. Appendix

Available in PDF, EPUB and Kindle. Book excerpt: Existing texts on the statistical mechanics of liquids treat only spherical molecules. However, nearly all fluids of practical interest are composed of non-spherical molecules that are often dipolar or exhibit other kinds of electrostatic forces. This book describes the statistical mechanical theory of fluids of non-spherical molecules and its application to the calculation of physical properties, and is a sequel to Theory of Molecular Fluids. Volume 1: Fundamentals by C.G. Gray and K.E. Gubbins. The emphasis is on the new phenomena that arise due to the non-spherical nature of the intermolecular forces, such as new phase transitions, structural features and dielectric effects. It contains chapters on the thermodynamic properties of pure and mixed fluids, surface properties, X-ray and neutron diffraction structure factors, dielectric properties and spectroscopic properties. The book is aimed at beginning graduate students and research workers in chemistry, physics, materials science and engineering.

Available in PDF, EPUB and Kindle. Book excerpt: Molecular simulation predictions of thermodynamic and transport properties of fluids such as water, electrolyte solutions, and CO2 are of considerable interest to energy, environmental, and industrial applications. The reliability and accuracy of these predictions are contingent on the molecular models used in simulation. Here, we investigate the predictive capabilities of several classes of molecular models, from simple empirical force fields to high dimensional machine learning (ML) models, in order to provide insight on the necessary physics for representing complex fluids.We first evaluate empirically derived polarizable, non-polarizable, and scaled charge models in representing the dynamic properties of aqueous electrolyte solutions. While polarizability improves structural and dynamic predictions, there re- main insufficient physics for achieving quantitative accuracy. The advent of ML frameworks applied to molecular models has made way for far more descriptive representations of water and electrolyte solutions, combining ab initio levels of accuracy with classical level computational costs. However, the lack of explicit long-range interactions in ML models remains a fundamental caveat. We investigate the consequences of this localized representation for various thermodynamic regimes of water and electrolyte solutions. We then construct ML models based on the SCAN DFT functional for several species of alkali halide electrolyte solutions which give thermo- dynamic properties with excellent agreement with experiments and dynamic properties which significantly improve upon that of conventional empirical force fields. Finally, we constructed many-body polarizable models of CO2 and assessed the influence of functional form flexibility and training set quality on bulk thermodynamic properties.The results in this thesis illustrate the limitations and scope by which several classes of molecular models, from empirical force fields to ML models, can be utilized reliably. Additionally, new ML models of electrolyte solutions and CO2 constructed in this work provide promising avenues toward studying complex fluid behavior from first principles perspectives.

Book excerpt: Molecular simulation is a very powerful technique that allows us to predict thermodynamic and transport properties of bulk and confined phases, as well as phase equilibria and interfacial properties. These properties are often crucial to the design of chemical and related industrial processes. Molecular simulation can predict these properties over a wide range of conditions, in contrast with experiments, which at extreme conditions (e.g., high temperature and/or high pressure) are often very difficult and in some cases dangerous. Further more, semi-empirical and empirical engineering models can frequently only be used for the specific systems to which they are fitted - that is, they are interpolative rather than predictive. Therefore molecular modeling methods, including simulation, can play a very useful role in the design of new processes, as well as the prediction of new phenomena. In this thesis, we applied molecular simulation methods to four separate problems: vapor-liquid equilibrium for a polarizable model of water, liquid-liquid interfacial properties, phase equilibrium in confined systems, and mechanical properties of nano scale systems. The first three problems imply the study of phases in equilibrium under different conditions. The most simple is the vapor-liquid equilibrium of a single component. Thermophysical properties such as coexistence densities, vapor pressure, surface tension, and interfacial thickness were obtained for a polarizable model of water and compared with other simpler potential models and experimental results. Using the same methodology, the interfacial properties of binary and ternary mixtures with polar and non-polar fluids exhibiting liquid-liquid equilibrium were studied. The dependence of the interfacial properties with increasing molecular size of one compound was studied. For ternary mixtures, the presence of a surfactant molecule was studied at different concentrations of the surfactant. Phase equilibria inside single carbon nanotubes were studied for single and binary aqueous systems, the coexistence liquid densities were calculated and compared with results of water in hydrophobic nanopores, and in the bulk. The phase equilibria behavior was studied indirectly in terms of the pressure inside the nanotube. Molecular simulation is a very suitable tool to study mechanical properties of systems at the nanoscale. The interlayer friction forces in double-wall carbonnanotubes were studied for systems with axial length up to 100 nm. The oscillatory behavior resulting when the inner tube is pulled out and released was studied as a function of nanotube length, temperature, and internal conformation. The latter enabled the study of systems with different degree of commensurability.

Final Technical Report, June 1, 1994--May 31, 1997 written by and published by . This book was released on 1997 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has been engaged in a research program aimed at enhancing the understanding of the thermo-physical properties of fluids containing long, flexible, chain-like molecules. She has been working on four main fronts: (1) the development of an equation of state that is capable of predicting the experimentally observed thermodynamic properties, including phase equilibria, of fluids containing chain-like molecules ranging in length from alkanes to polymers; (2) computer simulation studies of the transport properties of chain fluids, with special focus on the role played by entanglements in the dynamical properties of polymer melts, (3) computer simulation studies and theoretical treatment of the static and dynamic properties of polymer networks and gels, and (4) computer simulation studies of the permeation of penetrants in polymer membranes. The theories resulting from this research could eventually serve as the foundation upon which to build correlations of petroleum and natural gas, as well as of polymer solutions, melts, blends, networks, and gels. In this progress report the author summarizes work accomplished under DOE sponsorship of the period December 1993 to December 1996. In section 2, she summarizes the stated objectives of their previous (1993) proposal, indicating which work has been accomplished, which work is continuing, and which work has been discontinued. In section 3, she summarizes the three new objectives that were added after December 1993. In section 4, she provides a detailed description of the work accomplished, omitting those descriptions that appear in the accompanying proposal. In section 5, she describes their human resource development efforts. Finally, in section 6 she lists the publications resulting from this work. Abstracts of these papers are presented in the appendix.
