▼ The application of the Sanchez-Lacombe equation of state (SL-EOS) to homogeneous polymeric mixtures is requisite for the application of some types of Self-Consistent Field Theory (SCFT) to inhomogeneous mixtures. It has recently been observed that the SL-EOS fails to adequately describe the saturated polymer-solvent mixtures considered in polymeric foaming. This observation portends poor outcomes for the application of SCFT to the inhomogeneous polymer mixtures that constitute foams. In order to investigate this failure, an off-lattice method for deriving the SL-EOS is presented. In doing so, it is shown that the phase equilibrium inconsistencies introduced into the mixture formulation through hole volume mixing rules cannot be corrected, as previously proposed. Rather, it is found that any mixing rule applied to the hole volume introduces impermissible thermodynamic inconsistencies to the theory. A new variant of the theory for use with saturated polymer-solvent mixtures is proposed, eliminating mixing rules in favour of a constant hole volume. This variant is successfully applied to the solubility data of saturated binary and ternary polymer-solvent mixtures, indicating that the previously observed poor performance of the SL-EOS for such mixtures was partly the result of the thermodynamic inconsistencies. Fair agreement is also achieved for swelling data for the same mixtures. A physical interpretation of hole volume is put forward, characterizing them in terms of rudimentary averaged correlations. The interpretation relates these correlations to the architecture of polymer molecules, evidenced by consideration of both pure fluids and mixtures. The large number of conflicting literature parameters is addressed by proposing a best practice parameter estimation procedure based on nonlinear least-square fitting, for both for pure fluids and mixtures. Poor performance in some literature parameters is found to be related to sub-optimal parameter estimation practices, namely those that include few data points and those that encompass the critical point. An additional constraint is proposed for semi-empirical statistical thermodynamical theories that include features without physical basis and use thermodynamic principles to derive material properties, asserting that ensemble equivalence should be imposed. This constraint is applied through the imposition that equations of state derived from each thermodynamic potential be consistent.

▼ An extension to the off-lattice Sanchez Lacombe equation of state is proposed by including internal degrees of freedom to account for the finite flexibility of polymer molecules. The extension allows polymer molecules to have two energy levels of flexing, a ground/unflexed state and a degenerate excited/flexed state. The finite flexibility of polymer molecules is characterized by two regression parameters, the energy of excited states and their degeneracy. The flexibility parameters are regressed by using two experimental values: the glass transition temperature of pure polymers at atmospheric pressure and the change in isobaric heat capacity of pure polymers across the glass transition at atmospheric pressure. A method has been outlined to regress these parameters from experimental data. The glass transition temperature versus pressure and the isobaric heat capacity versus temperature predictions of the off-lattice model are compared with a lattice-based model from the literature. The lattice-based model is based on the Gibbs DiMarzio criterion which says that, at the glass transition, the configurational entropy of polymers becomes zero. However, the proposed off-lattice model shows that the Gibbs DiMarzio criterion is a consequence of the artificial lattice. Thus a new criterion is introduced which says that the glass transition occurs at a particular fraction of maximum polymer entropy that also minimizes the degeneracy of the excited state. Experimental data of several pure polymers are utilized to compare the predictions of both models. The proposed off-lattice model is found to be more accurate than the lattice-based model. The model is also employed to predict the glass transition temperature versus pressure behaviour of binary polystyrene/CO2, polycarbonate/CO2 and poly(methyl methacrylate) mixtures. Experimental solubility data is used to regress the binary interaction parameters of the system. The model predicts that the binary polystyrene/CO2 mixture shows depression in glass transition temperature with the increasing pressure of CO2. The prediction is in agreement with the experimental observations and is superior to the lattice-based model. However, for binary polycarbonate/CO2 and poly(methyl methacrylate)/CO2 mixtures that undergo retrograde vitrification, predictions for the present theory are not correct because underlying inconsistencies in the model make regressed values of binary interaction parameters less accurate. Nonetheless, using hand-picked values of binary interaction parameters, retrograde vitrification trend can be obtained.

▼ Application of carbon dioxide in polymer processing is a very attractive and innovative research area, driven by its significant impacts on environmental concerns, scientific and technological advancement and challenge. In this work, the interaction between CO₂ and polymer, including both bulk phase and thin film, has been addressed and modeled in order to guide the product and process development with the aid of CO₂2. An Axisymmetric Drop Shape Analysis (ADSA) method was developed to determine the CO₂-induced polymer dilation over a wide range of temperature and pressure. The experimental CO₂ sorption, polymer swelling and glass transition temperature (Tg) depression, have been successfully integrated with a single model, i.e., Sanchez-Lacombe Equation of State (SLEOS). Moreover, the benefits of CO₂ were demonstrated in the manufacturing of drug/polymer composite by reducing the operation temperature up to 35°C. Meanwhile, the anomalous polymer surface property, particularly Tg, was revealed in the development of CO₂-assisted polymer interfacial bonding technique. It is believed that the polymer surface has a lower Tg relative to its regular bulk value. An Atomic Force Microscopy (AFM)–based visualization method was developed to explore this surface phenomenon. The results demonstrated that CO₂ is able to further enhance the chain mobility near the surface region and allow the surface manipulation at lower temperatures. It has been hypothesized that shifts in the glass transition temperature in a polymer thin film or near a polymer surface is the result of liquid-like layer in that special region. We report here the first attempt to confirm this liquid-like layer theoretically by applying an inhomogeneous fluid theory combined with a chain molecule equation of state. Calculated entropy gradients in the surface region of a polymer reveal a liquid-like layer on the order of 1 nm at temperatures below the bulk Tg. This simple model provides a robust starting point for exploring the relation between experimentally observed anomalous properties and the inhomogeneities present near the surface.

Cette thèse vise à la production de poudre de polymère par un procédé continu, en une seule étape et supprimant l'utilisation des solvants organiques en faveur de celle du CO2 supercritique. Avant de développer le procédé, une caractérisation du mélange CO2/polymère a été effectuée. Des mesures de solubilité, de gonflement et de coefficient de diffusion du CO2 ont été réalisées et représentées par différents modèles. De plus, une technique de rhéologie capillaire en ligne a été développée, permettant la mesure de viscosité du polymère, seul ou en mélange, avec le CO2 dans les conditions du procédé. Un montage batch a ensuite permis de tester l'influence des paramètres opératoires sur de faibles quantités. Parallèlement, le procédé continu a été étudié sur une extrudeuse équipée d'outils de mélange du CO2 dans le polymère fondu. L'efficacité et l'homogénéité du mélange ont été étudiées à travers la fabrication de mousses de polymères et la réalisation de distributions de temps de séjour par spectroscopie Raman en ligne. L'ajout d'un dispositif de pulvérisation spécifique a conduit à l'obtention de poudres d'aspect fibreux avec deux populations de tailles.

Polymer powders are widely used in industry and are traditionally manufactured by processes using organic solvent or by grinding low molecular weight polymers with a post-polymerization step. This thesis aimss at the generation of polymer powders with a single-step continuous process, based on the use of supercritical CO2, hence without organic solvent. Before developing this process, the characterization of the mixture CO2/polymer was done. Solubility measurements were carried out and fitted with the Sanchez-Lacombe equation of state. Moreover, a capillary rheometry technique was implemented on-line, allowing the measurement of the viscosity of the polymer alone or in mixture with CO2, under process conditions. The modeling of swelling as a function of time led to the evaluation of the diffusion coefficient of CO2 into the polymer. Afterwards, two experimental devices were designed. A batch process with a pressurized autoclave was used to determine the influence of experimental parameters on powder production, with small amounts of material. Formation of small fibrous particles was obtained. In parallel, the continuous process was studied on an extruder adapted to CO2 introduction and equipped with mixing devices. This study, which led to foam manufacture, was used to evaluate efficiency and homogeneity of the mixing. Residence time distributions were determined by Raman spectroscopy on the die in order to evaluate the flowing in the extruder under different conditions. The equipment was also fitted with a specific nozzle allowing co-injection of hot air. Production of fibrous particles with two different size ranges was obtained.

▼ In this work, a parameterization strategy that allows the calculation of polymer molecular parameters from macroscopic properties of binary polymer solutions is presented. The proposed parameterization is demonstrated by reference to the PC-SAFT equation of state, but can be applied to any molecular-based model. The parameterization scheme has been developed in terms of the polymer-solvent interaction parameter and the Hildebrand parameter, which describe the molecular nature and extent of the polymer-solvent interactions. The specification of these macroscopic properties yields a set of polymer parameters that are suitable for the description of thermodynamic properties and phase behavior of polymer solutions. In this way neither extensive experimental data nor complex minimization techniques are necessary, as is required for the current approaches for the estimation of pure-polymer parameters for SAFT-type equations. Using polymer parameters calculated from the proposed parameterization strategy, the PC-SAFT model could satisfactorily predict the phase equilibria, gas solubility and polymer swelling behavior of binary and ternary polymer solutions with different solvents, including nonassociating compounds such as n-alkanes, polar compounds such as ethers, esters and ketones, and associating compounds such as alcohols. A computational approach for building atomistic models for amorphous polymer networks in order to simulate their pore structure and gas adsorption properties is also presented. The computational approach replicates the basic reactivity rules of the self-condensation reaction of dichloroxylene (DCX) via Friedel-Crafts chemistry and allows the formation of amorphous polymer networks, which are not possible to generate by structural X-ray crystallography/diffraction as is usually done for crystalline materials. The method is discussed for poly(dichloroxylene) networks, but can be extended to other polymer networks. Atomistic models were further refined by fitting to characterization data (i.e., bulk density, absolute density, micropore volume and elemental composition). These models were characterized by specific surface area and pore size distribution. A sensitivity analysis was performed to determine the minimum box size that should be used in adsorption simulations. Simulated adsorption isotherms and isosteric heats for methane and hydrogen were found to be in reasonable agreement with the experimental data.

▼ This thesis details research to understand the phase equilibrium associated with heterogeneous polymerizations in supercritical carbon dioxide (scCO2), particularly the polymerization of vinylidene fluoride (VF2) in scCO2. Knowledge of the equilibrium between the supercritical fluid and polymer phases may be applied to understanding the mechanisms involved in heterogeneous polymerizations in scCO2. Several experimental systems were developed and/or utilized for measuring the phase equilibrium. These included a system for measuring the swelling of solid polymer particles in the presence of scCO2, a system for measuring the mass sorption and diffusion of supercritical fluids into the polymer phase, and a system for measuring the partitioning of reactant species between the polymer and supercritical fluid phases. The sorption and swelling of poly(vinylidene fluoride) (PVDF) was measured at conditions similar to those of the polymerizations. The Sanchez-Lacombe equation of state was applied to modeling the binary and ternary phase equilibria for the VF2-CO2-PVDF system. Carbon dioxide exhibits a favorable interaction with PVDF that is enhanced at increasing fluid densities. Additionally, the monomer exhibits a favorable interaction with PVDF that improves the mass sorption into the polymer phase and expands the tunability of the fluid to change the polymer properties. The impact of the phase equilibrium on the precipitation polymerization of vinylidene fluoride in scCO2 is discussed. The bimodal molecular weight distribution of PVDF synthesized in CO2 could be due, in part, to the sorption of VF2 into the polymer phase and the plasticization of the polymer to facilitate propagation of the polymer chains to high molecular weights within the polymer particles. This dissertation provides a foundation for understanding the impact of the phase equilibrium on heterogeneous polymerizations in supercritical carbon dioxide. It provides techniques for identifying and improving conditions for polymerizations in supercritical carbon dioxide and optimizing CO2-based processes of a heterogeneous nature.

▼ The call for the advancement in our ability to design cleaner technologies, as well as mitigate our ecological footprint, requires the investigation of new energy related systems. Fundamental knowledge of the thermodynamics and phase behavior of such systems is essential for their development and industrial application. Accurate thermophysical properties are required, as limited or inaccurate data may affect the design of processes resulting in a financial or product yield loss; thus, the ability to reliably predict the properties and phase behavior of energy relevant fluids is essential to the development of new and continual improvement of existing chemical and energy processes. Traditional theoretical approaches based on semi-empirical or empirical equations of state that do not reflect molecular-level structure and interactions, are typically heavily reliant on correlations from experimental data, which may limit their general applicability. Molecular-based equations of state that take into account molecular structure are an attractive alternative because they yield a more accurate and predictive approach by accounting for the intrinsic effects of the microscopic interactions between molecules that ultimately determine the thermodynamic properties of the fluid. This results in parameters that are typically transferrable to entire classes of molecules. The statistical associating fluid theory for potentials of variable range (SAFT-VR) is one such molecular-based approach that describes chain molecules formed from hard-core monomers that interact via square well potentials of variable attractive range. In this work, systems with significant environmental applications, including carbon dioxide, organic sulfur and fluorine molecules, fatty acid methyl esters, and nanoparticle systems, are studied with the SAFT-VR approach. These systems were specifically chosen, as their unique features (e.g., large molecules, association interactions, electrostatics) have historically made their thermodynamic modeling difficult. Advisors/Committee Members: Peter Cummings (committee member), Doug LeVan (committee member), Mark Abkowitz (committee member), Clare McCabe (Committee Chair).

▼ In this thesis, I present a new equation of state for use in simulating supernovae, black holes and neutron star mergers. It is the first such equation of state for astrophysical applications to use a density functional theory description for hadronic matter. The inclusion of thermal effects of matter enable nuclear Skyrme models, which have been highly tested and constrained at laboratory energy scales, to expand their domain to predictions of astronomical phenomena. Broadening the scope of these models can further confine parameter sets, using vastly different energy scales. The new equation of state, titled the Notre Dame-Livermore Equation of State (NDL EoS), allows for the creation of a pion condensate at high density and pair production of all known baryonic and mesonic states at high temperature. The description of matter also allows for the possibility of the formation of a net proton excess (Ye > 0.5). In addition to the density functional theory formulation for hadronic matter, the NDL EoS contains low and high density completions to better describe matter in these specific energy regimes. The low density description expands upon a Bowers and Wilson formulation, adding a transition through nuclear pasta phases, which are of particular importance in neutron star structure. These low density definitions have further been updated to include an improved treatment of the nuclear statistical equilibrium and the transition to heavy nuclei as the density approaches nuclear matter density. At high densities, matter is allowed to transition to a quark-gluon plasma (QGP) either as a first-order Gibbs transition, or a smooth crossover. I identify predictions of the NDL EoS, contrasting them to existing equations of state and various Skyrme models of the NDL EoS. The observation of a heavy (two solar masses) neutron star restricts many descriptions of matter, and rules out several Skyrme parameter sets that had heretofore been entirely within the bounds set by nuclear experiments. Finally, I present the results of core-collapse simulations, both with the original Bowers and Wilson equation of state and the NDL EoS, using the spherically symmetric Mayle and Wilson supernova code.

Les travaux de cette thèse portent sur le développement de système microfluidiques génériques pour la mesure de propriétés thermodynamiques de solutions de proteines. Un procédé simple de fabrication de puces microfluidiques résistantes à la pression ainsi qu'à la majorité des solvants organiques a été développé. En outre, les propriétés de surface des microcanaux peuvent être ajustées afin de générer des émulsions eau dans huile ou huile dans l'eau. L'étude des interactions proteines-proteines en solution a été réalisée en couplant ces dispositifs expérimentaux à la diffusion de rayonnement X aux petits angles. Avec seulement quelque milligramme de produit, les données expérimentales obtenues ont permis de calculer le second coefficient du Viriel, grandeur thermodynamique permettant de quantifier les interactions entre protéines. Une nouvelle approche expérimentale a également été développée afin de déterminer l'équation d'état du lysozyme, équation reliant la pression osmotique à la fraction volumique. Ce système microfluidique est basé sur le transfert de matière entre d'une phase dispersée vers une phase continue. Dans une certaine gamme d'activité de l'eau, l'équation d'état obtenu est en bon accord avec les données de la littérature. Afin de relier la dynamique du transfert aux propriétés thermodynamique du système une première approche de modélisation est proposée. Cette approche a pour but de déterminer l'équation d'état de la protéine avec une seule goutte.

This thesis is focused on the development of more efficient protocols and systems, by means of generic microfluidic platforms for measuring thermodynamic properties of protein solutions. A simple method for manufacturing pressure-resistant microfluidic structures with high chemical resistance has been developed. In addition, the surface properties of the fabrication materials can be adjusted to generate hydrophilic and hydrophobic surfaces allowing to generate aqueous and non-aqueous emulsions. On a first approach, the study of protein-protein interactions in solution was successfully performed using just a few milligrams of product by coupling a microfluidic platform, developed ad-hoc for this application, to small angle X-ray scattering. The obtained experimental data were used to calculate the second virial coefficient, thermodynamic parameter which quantifies protein interactions. A second and new experimental approach has also been developed to determine protein equations of state (EOS), which relate protein osmotic pressure to its volume fraction in solution. This novel methodology is based on the study of the mass transfer between a dispersed and a continuous phase, which are generated and controlled by means of a microfluidic setup. For a given range of water activity, the resulting EOS was found to be in good agreement with data reported in the literature. To link the mass transfer dynamics to the thermodynamic properties of the system a first modeling approach was proposed. This approach aims to determine the EOS of the protein using a single…

▼ The accelerated expansion of the universe was discovered in 1998 through studying high–redshift Type Ia supernovae. “Dark energy” has been proposed to account for this acceleration. There have been sundry candidates for dark energy, which remains one of the greatest unresolved mysteries in science today. Einstein's cosmological constant Λ originally introduced in 1917 became a strong candidate for dark energy. A model of the universe with cold dark matter (CDM) and a cosmological constant, the ΛCDM, became the currently accepted model of the universe. However, there are distinct unresolved issues with the ΛCDM cosmology, one major one being the coincidence problem. There are also realistic models of the universe, such as quintessence cosmologies which contain a scalar field <i>Φ</i>, hypothesized to be time–varying dark energy, that have been proposed. In the cyclic phantom model, the universe is dominated sequentially by radiation, matter, and a phantom dark energy field, followed by a standard inflationary phase. Since this cycle repeats endlessly, the universe spends a substantial portion of its lifetime in a state for which the matter and dark energy densities have comparable magnitudes, thus ameliorating the coincidence problem. In inflection point quintessence, a cosmology invented by the author and her advisor, the accelerated expansion of the universe is driven by a scalar field rolling near an inflection point in the potential. For the simplest such models, in which the potential is of the form <i>V(Φ) = V₀ + V₃ (Φ – Φ₀)³</i>, the scalar field can yield an eternal or a transient acceleration. The cases that imitate the ΛCDM can be consistent with either outcome. Finally, a quintessence model with a modified exponential potential given by <i>V(Φ) = V₀ (1 + e^–λΦ)</i> can produce an acceptable accelerated expansion at late times. The strongest constraints on the model from Cosmic Microwave Background observations give the limit <i>λ</i> > 13. This cosmology provides a partial solution to the coincidence problem. The above three models of the universe contain scalar fields. The goal of this dissertation is to further the revelation of dark energy by providing ideas for more accurate models of the universe.

▼ Chemical process design requires mathematical models for predicting thermophysical properties. Those models, called equations of state (EoS), need experimental data for parameter estimation and validation. This work presents a detailed description of a vibrating tube densimeter, which is an alternative technique for measurement of p-ρ-T data in gases at critical conditions. This apparatus can measure fluids in a temperature range of 300 K to 470 K and pressures up to 140 MPa. This work calibrates the vibrating tube using a physical-based methodology with nitrogen, methane and argon measurements. Carbon dioxide and ethane p-ρ-T data validate calibration procedures covering a wide range in density and pressure. The vibrating tube densimeter performs density measurements for nitrogen + methane mixtures for pressures up to 140 MPa. This work also presents a new equation of state (EoS) having a rational form that can describe properties with accuracy comparable to the best multi-parametric equations with less mathematical complexity. This EoS presents the Helmholtz residual energy as a ratio of two polynomial functions in density (no exponential terms in density are included), which can describe the behavior of pure components. The EoS can be transformed to describe other thermophysical properties as pressure, compressibility factor, heat capacity and speed of sound. Also this equation can calculate saturated liquid-vapor properties with 20 times less computational time. This work presents rational EoS for nitrogen, argon and methane applicable in wide ranges of pressure and temperature. Finally, this work proposes a new mixing rule for binary mixtures of gases based upon a quadratic combination of residual Helmholtz energy. This approach divides the energy contribution between interactions of same species and interaction of different species molecules. A rational form is proposed for description of energy interaction between molecules of different species. The mixing rule is applied to nitrogen + methane data.

▼ Access to energy is essential for the survival of humans, and the need for energy rises continuously because of population increase and economic progress. Fossil fuels continue to play the major role in satisfying energy demand. Among the fossil fuels, natural gas is the cleanest, most available, and most useful of the energy sources. It finds extensive use in residential, commercial, electric power generation and industrial applications. Moreover, the international energy outlook report released in 2011 indicates that yearly world natural gas consumption should increase from 111 trillion cubic feet in 2008 to 169 trillion cubic feet in 2035. Recently, new natural gas reservoirs have been discovered in many places throughout the world. In 2012, the total world supplies of proved natural gas reserves were estimated to be 6,746.8 trillion cubic feet. Thus, studies on natural gas are significant to advance the technique of natural gas processing, transportation and storage. In these three sectors, an accurate knowledge of the thermodynamic properties of natural gas is essential for engineering and technical processes. Developing accurate equations of state is important, and can provide us with accurate thermodynamic properties for natural gas. In addition, developing new techniques to produce mathematical models is important to create more accurate results and to enrich this field with new ideas, which might provide progress in the future. The aim of this thesis is to demonstrate a new approach for developing an equation of state. This technique relies upon isochoric data of carbon dioxide pure component to develop mathematical models. This thesis contains nine models based upon experimental and generated data. The generated data come from REFPROP, which also provides an accurate means to adjust experimental data to true isochores. Within this thesis, a regression analysis was performed - using Polymath 6.1 - to provide mathematical structure of the equation for carbon dioxide. Results indicate that models covering vapor phase has less deviation than models covering liquid or both phases, and models developed by the generated data has less deviation than models developed by the experimental data. The deviation obtained by most of the models was less than the random error imposed upon the data. In this study, we conclude that modeling an equation of state from isochores appears to provide sufficient advantages to encourage additional studies on pure fluids and multi-component mixtures.

▼ In 2013, the United States Geological Survey (USGS) released an estimate of 7.38 billion barrels of oil held within the Bakken Formation, one of the most significant discoveries. However, the Bakken Formation, a tight shale play, is also known for its ultra-low permeability and nano-scale pore size (1 – 100 nm). A nano-scale pore size can impact the petroleum fluid properties when compared to its bulk properties. This study utilized a theory-based analytical method and compares the results with those from experiments conducted under the simulated conditions. Peng-Robinson Equation of State (PR-EOS) was modified to calculate the critical properties of individual hydrocarbon component in confined conditions. The modification was deduced from the Helmholtz free energy function with Lennard-Jones potential for particles interaction. The modified PR-EOS became a function of molecule-to-pore-size ratio. The value of pore size was obtained using nuclear magnetic resonance (NMR) and from related experiments. NMR measurements were conducted on five-Middle Bakken core samples and provided the pore size distribution and porosity. The results from the analytical method and experiments were compared with the data from the literature to examine the theory and for comparison purposes. Suppression effect on critical temperature was calculated on eight hydrocarbons (from methane to decane) and compared with the experimental results. The total porosity from five- NMR experiments, is within the range of 2.73 to 9.38 % with an average of 5.4 %. A close match was found between the model and experiments with a deviation of 14% for pore sizes within 1 – 3 nm and of 1.02% for pore sizes larger than 3 nm. The pore size of 3 nm seems to work as a cutoff due to the adsorption layers on the vicinity of the pore wall. Also, the bulk critical properties were estimated using the equations and presented similar results to the literature, with a maximum deviation of 0.03%. Advisors/Committee Members: Hadi Jabbari.

▼

The history of planet formation and evolution is strongly tied to understanding the outcomes of a wide range of impact events, from slow accretionary events to hypervelocity events that melt and vaporize large fractions of the colliding bodies. To better understand impact processes, their effects on planetary evolution, and how to interpret geochemical data, we need to improve our knowledge of the behavior of materials over the entire range of conditions accessed by collisions. Here I present experimental results from gas gun, laser driven, and pulsed power facilities. Together these facilities can access the tremendously wide range of pressure and temperature conditions achieved in natural impact events. This work focuses on the thermodynamics of impacts to better understand the phase transitions that most strongly affect the dynamics and chemical consequences of a collision. I show that the entropy generation during collisions is the most natural means of interpreting the thermodynamic processes that occur during an impact event. For materials with sufficient thermodynamic data at high pressures and temperatures, I present a method for obtaining the entropy generation during an impact. With the knowledge of the entropy, I present new shock-and-release techniques to investigate the liquid-vapor region of the phase diagram. I also show that for materials without sufficient data to calculate the entropy generation during an impact, one can use the shock-and-release techniques described here to determine the entropy in the high pressure shock state. With better equation of state models that are constrained by our experimental data, our confidence in impact models improves dramatically. Using a high fidelity equation of state for (H_2O). ice, I derive scaling laws for how much (H_2O) ice melts and vaporizes for impacts onto icy bodies. Recognizing that icy bodies are not pure ice, I have performed experiments to show how the impact energy partitions between the disparate phases. Finally, I discuss some of the uncertainties in using the laboratory experiments to directly interpret the effects of impacts in nature.

▼ Based on the relation suggested by Hudson and McCoubery, we proposed new mixing rules for the coefficients of the modified generalized BWR equation of state in a previous work. We found that the binary interaction parameter, mij in the mixing rules were correlated as a function of the ratio of critical molar volume in previous work. Using the previous correlated functions of mij, we examined the prediction abilities of the VLE (vapor - liquid equilibria). As a result, we had good predictions except for binary systems containing of nitrogen or aromatic hydrocarbons. Therefore, we determined the optimal mij of various binary systems and reconsidered the classification of mij. We re-correlated the functions and could change the functions into simpler one. The validity of the present correlation is ascertained by the calculation of VLE for various binary systems and ternary systems. We obtained better results than previous work.工業上、熱力学的物性値が必要になった場合、状態方程式により推算する方法がよく用いられている。しかし、混合物の気液平衡関係などの熱力学的物性値を推算するには、異種分子間の相互作用を補正する項が必要になる。一般的に、この項は気液平衡関係を良好に示すように決定されるが、これでは少ない物性値から多くの熱力学的物性値を計算できるという状態式の優位性は失われてしまう。当研究室では、以前Hudson-McCoubreyの理論に基づき、異種分子間相互作用係数mijが臨界容積の比Vci/Vcjの関数になることを発見し、mijは似通った化学種ごとに9グループ、12本に分類することで相関可能であることを示している。本研究では、この相関式から求めたmijを使用して計算した気液平衡推算値とその実験値との偏倚を評価し、式の妥当性を検討した。多くの系で一定の結果を得たが、不十分な系もあったため、グループの分類法自体の評価・検討、相関式の再決定を行った。アルカン・アルケン・シクロアルカンを含む系は、メタンを除くと一つのグループとしてまとめられる事が分かった。また、窒素と一酸化炭素のグループ、硫化水素、二酸化炭素、アセチレンのグループとして、それぞればらばらに分類されていたものをまとめられることが分かった。結果として、４本の相関式でこれまで扱っていた物質を表現できる事が分かった。簡潔さだけではなく、気液平衡関係などの物性値をさらに良好に示せるようになった。

▼ Modern mining explosives employ solutions of ammonium nitrate, where the solution is the oxidising component of a fuel/oxidiser mixture. This thesis is primarily concerned with the shock response of water and of aqueous solutions of ammonium nitrate. Of particular interest are the temperatures induced through shock compression. An experimental facility, using a single stage gas gun in the ‘plate impact’ configuration, is described, along with associated experimental diagnostics. Measurements of, and improvements to, the tilt at impact are reported. The problem of shock temperature is discussed, including a brief review of the relevant literature. It is demonstrated that direct measurement of shock temperature is a complex issue that is not yet fully understood, whereas determination of temperature from an equation of state is an established technique. In a series of experiments, plate impact techniques were utilised to determine the Hugoniot and, through shock/reload experiments, the equation of state of water and aqueous solutions of ammonium nitrate. In-situ manganin gauges were used to measure stresses in the liquids and, from the arrival times of the shock wave, determine the shock velocity. Linear shock velocity–particle velocity Hugoniots for the liquids were determined, up to particle velocities of 1km/s, with uncertainties on the intercept and slope of these Hugoniots of 5%. A Mie-Grüneisen equation of state was used to describe the shock/reload experiments. Approximate calculations of shock temperature are reported. Increasing ammonium nitrate concentrations resulted in greater calculated temperatures. It was demonstrated that the liquids investigated in this thesis show a temperature dependence of the Grüneisen parameter, Г, which cannot be accommodated in the model. The present work is believed to be the first demonstration of this effect in shock compressed liquids. The data presented provide constraints on future theoretical development of equations of state.
