▼ Miscible gas injection processes could be among the most widely used enhanced oil recovery processes. Successful design and implementation of a miscible gas injection project depends upon the accurate determination of the minimum miscibility pressure (MMP) and other factors such as reservoir and fluid characterization. The MMP indicates the lowest pressure at which the displacement process becomes multicontact miscible. The experimental methods available for determining MMP are both costly and time consuming. Therefore, the use of correlations that prove to be reliable for a wide range of fluid types would likely be considered acceptable for preliminary screening studies. This work includes a comparative and critical evaluation of MMP correlations and thermodynamic models using an equation of state by PVTsim software. Application of gas injection usually entails substantial risk because of the technological sophistication and financial requirements to initiate the project. More detailed, comprehensive reservoir engineering and project monitoring are necessary for typical miscible flood projects than for other recovery methods. This project evaluated effects of important factors such as injection pressure, vertical-to-horizontal permeability ratio, well completion, relative permeability, and permeability stratification on the recovery efficiency from the reservoir for both miscible and immiscible displacements. A three-dimensional, three-phase, Peng-Robinson equation of state (PR-EOS) compositional simulator based on the implicit-pressure explicit-saturation (IMPES) technique was used to determine the sensitivity of miscible or immiscible oil recovery to suitable ranges of these reservoir parameters. Most of the MMP correlations evaluated in this study have proven not to consider the effect of fluid composition properly. In most cases, EOS-based models are more conservative in predicting MMP values. If screening methods identify a reservoir as a candidate for a miscible injection project, experimental MMP measurements should be conducted for specific gas-injection purposes. Simulation results indicated that injection pressure was a key parameter that influences oil recovery to a high degree. MMP appears to be the optimum injection pressure since the incremental oil recovery at pressures above the MMP is negligible and at pressures below the MMP recovery is substantially lower. Stratification, injection-well completion pattern, and vertical-to-horizontal permeability ratios could also affect the recovery efficiency of the reservoir in a variety of ways discussed in this work.

Cette étude porte sur la production et la caractérisation de fils élastomères à base de polypropylène (PP) et d’élastomères thermoplastiques (TPE). L’étude du filage par voie fondue des polymères sous forme de mélanges montre une relation entre les propriétés des fibres et la morphologie du mélange. Les propriétés élastiques ne sont améliorées qu’avec le changement de morphologie, et le passage à une matrice TPE majoritaire. Les mélanges filés avec un taux de TPE élevé (80 et 90%m) montrent un changement de structure cristalline du TPE, qui augmente la récupération élastique. L’étude du filage sous forme de structure bicomposante cœur/gaine (C/G), où le TPE est introduit dans le cœur de la fibre et le PP en gaine, montre l’influence du rapport massique C/G sur les propriétés mécaniques des multifilaments. Les propriétés élastiques ne sont pas améliorées pour les différents rapports massiques C/G étudiés, en raison du comportement plastique de la gaine. Le meilleur compromis en termes de propriétés et de mise en œuvre est obtenu avec une structure hybride. Le multifilament mis en œuvre est un fil bicomposant C/G, mais avec un mélange TPE/PP en gaine et le TPE vierge en cœur. Les résultats montrent toujours une diminution des propriétés mécaniques avec l’augmentation du rapport massique C/G, mais une amélioration de la récupération élastique est observée. Pour des taux de TPE équivalents, les propriétés de la structure hybride sont supérieures à celles déterminées pour les mélanges sous forme de fibres monocomposantes. Pour finir des essais de texturation et de tissage démontrent une possible utilisation de ces multifilaments dans des procédés de transformation textile.

The aim of this work is the study of elastomeric fibers processed by melt spinning of polypropylene (PP) and thermoplastic elastomers (TPE). Multifilaments produced by a melt spinning process of polymers blend show a relationship between fiber properties and their morphology. Elastic properties are enhanced only when the majority phase is TPE. Yarns melt spun from blends with high TPE rates (80 and 90 wt.%) show a transition of the crystal structure from pseudo hexagonal to orthorhombic with the increase of drawing ratio applied which improve elastic recovery. Melt spinning of core/sheath (C/S) bicomponent fibers is performed using TPE as the core and PP as the sheath. The study reveals a decrease in mechanical properties with increasing the C/S ratio, and elastic properties are not modified for the different C/S ratios studied. This behavior can be explained by the plastic deformation of the polypropylene sheath. In order to improve processability and properties, melt spinning of core-sheath bicomponent fibers with different C/S ratios is performed using EOC and polypropylene blends as the sheath and pure EOC as the core. The results still show a decrease in mechanical properties with the increase in the C/S ratio, but elastic properties are enhanced. For the same TPE content, elastic recovery and mechanical properties are higher for hybrid fiber…

▼ The current practice for recycling of mixed plastics relies on complex and time-consuming procedures for materials separation or the use of expensive compatibilizers for improving mechanical properties. A simple method for direct reuse of waste plastics without the pre-separation procedure or the compatibilizer will be beneficial for efficient and cost-effective recycling. This emerging need provides a motivation to study how to process immiscible polymer blends into value-added fiber-based products without using compatibilizers, which, on the other hand, are also helpful for the development of new polymer blend products. In this thesis study, we adopt a “nearly co-continuous structure” and employ such a morphology for materials processing and products realization when immiscible polymer blends are encountered. This nearly co-continuous structure is considered significant from both engineering and economics perspectives. The thesis starts with constitutive modeling of the dynamics of complex interfaces, leading to equations for the Cauchy stress tensor and the evolution of interfacial orientation in both affine deformation and situations where relaxing effects need to be considered. With the help of constitutive modeling and characterization, a methodology has been designed for producing valuable fiber-based products from immiscible polymer blends. Two case studies are used to demonstrate the methodology. Fiber prepared from the PP/PS blend shows improved mechanical properties compared with the fiber obtained via traditional melt spinning. In addition to improved mechanical properties, efforts have also been made to process polymer blend products with novel properties. Particularly, PCL/OBC blend is used as a model system to produce reusable supercontraction fiber which possesses a supercontraction ability upon heating. The overall methodology developed in this thesis work is formulated on the basis of the interfacial dynamics during blends processing where a compatibilizer is absent. Therefore, it may provide a potential route for direct recycling of waste plastics without the use of compatibilizers.

▼ The correct description of multiphase flow mechanism in porous media is an important aspect of research in fluid mechanics, water resources and petroleum engineering. The thorough understanding of these mechanisms is important for many applications such as waterflood, CO2 sequestration, and enhanced oil recovery. Being different from single phase flow that is well described by Darcy’s law and well understood for over 160 years, the multiphase flow mechanism requires more mathematical involvement with more complex fluid interaction which inevitably will incorporate relative permeability and capillary pressure into its description. For typical two-phase flow problems, especially at the conventional reservoir scale, the Buckley-Leverett flow equations are normally applied with negligible capillarity to capture the flow behavior. However, as we extend our studies to higher resolution using multiscale calculations, or evaluate tighter or higher contrast heterogeneous reservoirs, capillarity becomes increasingly important. Also, for situations such as spontaneous imbibition that wetting fluid is displaced by non-wetting invading fluid, it is possible that capillary force becomes the dominating driving force with negligible viscous and gravity contributions. To better characterize the multiphase flow mechanism with capillarity, in this research, a detailed investigation is carried out in pursuit of more rigorous mathematical description and broader applicability. The numerical simulation analysis of the described problem has long been a subject of interest with numerous publications addressing it. Being different from the traditional methods where numerical simulation is used, we pursue the analytical description of the flow behavior using Lagrangian approach which is better in describing these frontal propagation problems. Also, the analytical solution tends to give more insight into the underlying physical characteristics of the problem itself. As one of the most important outcomes, the methodology derives a new dimensionless capillary group that characterizes the relative strength of capillarity at the continuum scale based on the analytical solution. Knowledge of this can be used for stability analyses, with future potential application in the design of computational grids to properly resolve the capillary physics.

▼ There exist many practical examples of extreme environments where materials are commonly forced to operate, ranging from nuclear reactors to alloys being processed through severe plastic deformation. In each of these cases, there exists external dynamical forcing which keeps the material in non-equilibrium conditions. In the case of structural materials in a nuclear reactor environment, there are high fluxes of neutrons which can cause the alloys to become microstructurally unstable and cause their properties to change over time. In addition, nuclear reactors are kept at high temperatures in order to generate power, which can cause other deleterious effects on a material such as creep and grain coarsening. For severe plastic deformation processing of alloys, such as high energy milling, a large amount of energy is imparted in the form of stress, which causes dislocation motion and grain refinement. Temperatures can also vary depending on the process, generally ranging from room temperature to > 0.75 of the melting point. Because each of the environments listed contains an external dynamical force which is driving the materials into non-equilibrium, they are commonly referred to as driven materials. Due to the number of external factors and the numerous practical situations involving driven materials, one may ask if there is a theoretical framework on in which it is possible to not only describe what is occurring but to also predict how the material’s microstructure will evolve over time. After gaining the understanding to be able to predict the material response to such extreme environments, it would be especially beneficial to find a class of materials which would remain stable over time. In other words, rather than determining when an alloy would fail under service, it would be best if it were possible to design an alloy which would simply never fail over its expected lifetime. To achieve this goal, research has been conducted in material science to better understand the fundamentals of driven materials. One of the main areas of focus revolves around the idea of self-organization in nanostructured alloys. A material which self-organizes will reach a steady state microstructure and will not change as long as the environmental parameters do not change. This means that a material which self-organizes would have the same microstructure indefinitely, even in an environment as extreme as a nuclear reactor, and would not undergo the negative effects such as coarsening or phase changes. The property of self-organization has been readily identified in moderately immiscible and highly immiscible alloy systems such as Cu-Ag or Cu-W, respectively. Furthermore, this behavior is experienced in multiple driven systems; both irradiation and severe plastic deformation (SPD) have been shown to share very similar characteristics, even though the underlying mechanisms are different. While existing models such as the “Driven System Model” and “Effective Temperature Model” can explain existing experimental results for alloys systems… Advisors/Committee Members: Bellon, Pascal (advisor), Averback, Robert (Committee Chair), Dillon, Shen (committee member), Maass, Robert (committee member).

▼ Immiscible liquids, including chlorinated solvents, have proven to be a lasting source of subsurface contamination at many hazardous waste sites. Continued improvement of site characterization and determination of applicable remediation technologies can be achieved by further understanding of the transport and fate of these contaminants. The transport and fate of trichloroethene (TCE) was investigated through miscible displacement and dissolution experiments. Miscible displacement experiments were conducted using homogeneously packed columns with several porous media encompassing a range of particle size distributions. Immiscible liquid dissolution was investigated using homogeneously packed columns containing a residual saturation of trichloroethene. The same porous media were used for immiscible liquid dissolution experiments. Mathematical modeling of miscible displacement and dissolution experiments was conducted using a one-dimensional single region or multi-region model. Imaging of immiscible liquid dissolution was also conducted, using Synchrotron X-ray Microtomography imaging at Argonne National Laboratory, Argonne, IL. Dissolution experiments exhibited nonideal dissolution behavior that was apparent in observed effluent data and in collected imaging data. Nonideal behavior was manifested as secondary regions of relatively constant aqueous concentrations occurring for a number of pore volumes. This behavior was observed to increase in magnitude as particle size distribution of the porous media increased. During imaging, immiscible liquid blobs were observed to dissolve throughout the column during dissolution. This behavior is also indicative of nonideal dissolution, as it would be expected that dissolution would first occur for the blobs nearest the inlet and then proceed upward through the column as dissolution progressed. In many cases, a multi-region modeling approach was necessary to successfully represent the nonideal behavior observed. Comparisons were made between the natural porous media used for this research and a well-sorted sand. Nonideal dissolution was not observed in the well-sorted sand.

▼ Free machining alloys containing soft immiscible phases in the aluminium (Al) matrix, like lead (Pb) and bismuth (Bi), are of great industrial interest. Typical applications in automotive industry are components requiring very high machinability, such as braking pistons and antiblocking system (ABS) housings. Presence of soft immiscible phases is giving their machining properties to this class of alloys. These phases melt due to localised heat build-up generated by machining process and induce chips breaking. Such type of alloys offers best in class performance when the soft phase is uniformly distributed in the Al matrix. The main objective of this work was to develop a method to tailor the distribution of the immiscible phase particles in the final solidified structure of DC cast billets in order to provide enhanced machinability while keeping low levels of Pb and/or Bi additions. As a consequence, another objective of this study was to improve recyclability of such alloys as well as to reduce their environmental impact. Three categories of Al-Pb alloys and different solidification paths were studied: hypermonotectic Al-3Pb, monotectic Al-1.2Pb and industrial hypo-monotectic free machining alloy containing both Pb and Bi. A newly developed melt conditioning combines mechanical, thermal and chemical treatments to obtain a very fine and uniform distribution of the immiscible phase droplets and eliminate compositional heterogeneities. The effect of these new melt treatments on microstructure was evaluated. For the soft phase droplets size was reduced and distribution becomes finer and more homogeneous under the individual effect of each of the treatments and optimum results obtained with the combination of them. These new melt treatments affect not only the nucleation of the Pb/Bi droplets, enhancing their heterogeneous nucleation but reduces considerably the Marangoni motion and Stokes sedimentation reducing therefore the droplet coalescence and restricting their growth. As a consequence of this improved microstructure, mechanical properties and machining performance were enhanced considerably. The results from this study provide a promising new microstructure with a fine and uniform distribution of droplets.

▼ This work presents a novel method to model immiscible incompressible fluids in a stable manner. Here, the immiscible behavior of the flow is described by the incompressible Navier-Stokes-Cahn-Hilliard model, which is based on a diffuse interface method. We introduce buoyancy effects in the model through the Boussinesq approximation in a consistent manner. A structure-preserving discretization is used to guarantee the linear stability of the discrete problem and to satisfy the incompressibility of the discrete solution at every point in space by construction. For the solution of the model, we developed the Portable Extensible Toolkit for Isogeometric Analysis with Multi-Field discretizations (PetIGA-MF), a high-performance framework that supports structure-preserving spaces. PetIGA-MF is built on top of PetIGA and the Portable Extensible Toolkit for Scientific Computation (PETSc), sharing all their user-friendly, performance, and flexibility features. Herein, we describe the implementation of our model in PetIGA-MF and the details of the numerical solution. With several numerical tests, we verify the convergence, scalability, and validity of our approach. We use highly-resolved numerical simulations to analyze the merging and rising of droplets. From these simulations, we detailed the energy exchanges in the system to evaluate quantitatively the quality of our simulations. The good agreement of our results when compared against theoretical descriptions of the merging, and the small errors found in the energy analysis, allow us to validate our approach. Additionally, we present the development of an unconditionally energy-stable generalized-alpha method for the Swift-Hohenberg model that offers control over the numerical dissipation. A pattern formation example demonstrates the energy-stability and convergence of our method. Advisors/Committee Members: Parsani, Matteo (advisor), Calo, Victor M. (advisor), Keyes, David E.

▼ This thesis reports development of a new constitutive model to describe stress in blends consisting of immiscible Newtonian fluids. It adopts the theory of Doi-Ohta as the foundation of the model. While the description of droplet deformation was adopted from the Doi-Ohta theory, the relaxation of droplets and blends was developed to account for the blend's discontinuous nature. Three relaxation mechanisms are ultimately incorporated into the constitutive model: retraction, breakup and coalescence. The retraction term was formulated in a way that conserves an invariant function that approximates droplet volume. Step shear experiments showed that flat, extended droplets after the step shear relax into axisymmetric ellipsoids before they finally relax to spherical shapes. The retraction model successfully captures this behavior. Furthermore, the model was also used to describe the shapes and stresses of droplets and blends during high shear deformation with satisfactory results. The breakup description was adopted from the Tomotika theory, according to which an extended thread of a viscous fluid that is immersed in another develops sinusoidal instabilities on its surface prior to breakup. Large step-shear experiments were carried out to verify the model. It was found that when droplet end-cap effects were excluded, agreement with breakup model predictions occurred even at strains that were only slightly greater than necessary for breakup. The ability to describe the coalescence process is tied to the ability to accurately describe droplets at mild flow fields and large strains. The accuracy of the model was improved by using a better droplet volume description and a more accurate description for deformation of droplets. The coalescence description was incorporated into the model, and its predictions were then successfully compared to literature experimental data. This comprehensive model is one of the first that incorporates descriptions for deformation, retraction, breakup and coalescence modes. The model was compared to shear flow start-up data, where all such modes can potentially take place, and a qualitative agreement was achieved. Moreover, model predictions of droplet size as a result of applied deformation were found to be in qualitative agreement with theoretical predictions. Advisors/Committee Members: Larson, Ronald G. (advisor), Solomon, Michael J. (advisor).

Cette thèse est centrée autour du développement et de l'analyse des schémas volumes finis robustes afin d'approcher les solutions du modèle diphasique compressible en milieux poreux hétérogènes et anisotropes. Le modèle à deux phases compressibles comprend deux équations paraboliques dégénérées et couplées dont les variables principales sont la saturation du gaz et la pression globale. Ce système est discrétisé à l'aide de deux méthodes différentes (CVFE et DDFV) qui font partie de la famille des volumes finis. La première classe à laquelle on s'intéresse consiste à combiner la méthode des volumes finis et celle des éléments finis. Dans un premier temps, on considère un schéma volume finis upwind pour la partie convective et un schéma de type éléments finis conformes pour la diffusion capillaire. Sous l'hypothèse que les coefficients de transmissibilités sont positifs, on montre que la saturation vérifie le principe du maximum et on établit des estimations d'énergies permettant de démontrer la convergence du schéma. Dans un second temps, on a mis en place un schéma positif qui corrige le précédent. Ce schéma est basé sur une approximation des flux diffusifs par le schéma de Godunov. L'avantage est d'établir la bornitude des solutions approchées ainsi que les estimations uniformes sur les gradients discrets sans aucune contrainte ni sur le maillage ni sur la perméabilité. En utilisant des arguments classiques de compacité, on prouve rigoureusement la converge du schéma. Chaque schéma est validé par des simulations numériques qui montrent bien le comportement attendu d'une telle solution. Concernant la deuxième classe, on s'intéressera tout d'abord à la construction et à l'étude d'un nouveau schéma de type DDFV (Discrete Duality Finite Volume) pour une équation de diffusion non linéaire dégénérée. Cette méthode permet d' avantage de prendre en compte des maillages très généraux et des perméabilités quelconques. L'idée clé de cette discrétisation est d'approcher les flux dans la direction normale par un schéma centré et d'utiliser un schéma décentré dans la direction tangentielle. Par conséquent, on démontre que la solution approchée respecte les bornes physiques et on établit aussi des estimations d'énergie. La convergence du schéma est également établie. Des résultats numériques confirment bien ceux de la théorie. Ils exhibent en outre que la méthode est presque d'ordre deux.

The objective of this thesis is the development and the analysis of robust and consistent numerical schemes for the approximation of compressible two-phase flow models in anisotropic and heterogeneous porous media. A particular emphasis is set on the anisotropy together with the geometric complexity of the medium. The mathematical problem is given in a system of two degenerate and coupled parabolic equations whose main variables are the nonwetting saturation and the global pressure. In view of the difficulties manifested in the considered system, its cornerstone equations are approximated with two different classes of the finite volume family.…

▼ Microfluidic devices are utilized in a wide range of applications, including micro-electromechanical devices, drug delivery, biological diagnostics and micro-fuel cell systems. Of particular interest here are liquid-liquid microfluidic systems; which are used in drug discovery, food and oil industry amongst others. Increased understanding of the fundamentals of flows in such devices and an improved capacity to design them can come from modelling. In the case of liquid-liquid flows in microfluidic systems, it is necessary to explicitly model the behaviour of the individual liquid phases. Such explicit numerical simulation (ENS) as it is termed requires advanced numerical methods that are able to evaluate flow involving multiple deforming fluid domains within often complex boundaries. Smoothed Particle Hydrodynamics (SPH), a Lagrangian meshless method, is particularly suitable for such problems. This use of a CFD allows determination of parameters that are difficult to determine experimentally because of the challenges faced in microfabrication. The study reported in this thesis addresses these concerns through development of a new SPH-based model to correctly capture the immiscible liquid-liquid interfaces in general and for a microfluidic hydrodynamic focusing system in particular. The model includes surface tension to enforce immiscibility between different liquids based on a new immiscibility model, enforces strict incompressibility, and allows for arbitrary fluid constitutive models. This work presents a detailed study on the effects of various flow parameters including flowrate ratio, viscosity ratio and capillary number of each liquid phase, and geometry characteristics such as channel size, width ratio, and the angle between the inlet main and side channels on the flow dynamics and topological changes of the multiphase microfluidic system. According to our findings, both flowrate quantity and flowrate ratio affect the droplet length in the dripping regime and a large viscosity ratio imposes an increase in the flowrate of the continuous phase with the same capillary number of the dispersed phase to attain dripping regime in the outlet channel. Also, increasing the side channel width causes longer droplets, and the right-angled design makes the most efficient focusing behaviour. This study will provide great insights in designing microfluidic devices involving immiscible liquid-liquid flows. Advisors/Committee Members: Biggs, Mark James (advisor), Alwahabi, Zeyad T.

▼ Microfluidic devices can be used for many applications, including the formation of well-controlled emulsions. In this study, the capability to continuously create monodisperse droplets in a microfluidic device was used to form calcium-alginate capsules.Calcium-alginate capsules have many potential uses, such as immunoisolation of cells and microencapsulation of active drug ingredients or bitter agents in food or beverage products. The gelation of calcium-alginate capsules is achieved by crosslinking sodiumalginate with calcium ions. Calcium ions dissociated from calcium carbonate due to diffusion of acetic acid from a sunflower oil phase into an aqueous droplet containing sodium-alginate and calcium carbonate. After gelation, the capsules were separated from the continuous oil phase into an aqueous solution for use in biological applications. Typically, capsules are separated bycentrifugation, which can damage both the capsules and the encapsulated material. A passive method achieves separation without exposing the encapsulated material or the capsules to large mechanical forces, thereby preventing damage. To achieve passiveseparation, the use of a microfluidic device with opposing channel wa hydrophobicity was used to stabilize co-laminar flow of im of hydrophobicity is accomplished by defining one length of the channel with a hydrogel. The chosen hydrogel was poly (ethylene glycol) diacrylate, which adheres to the glass surface through the use of self-assembled monolayer of 3-(trichlorosilyl)-propyl methacrylate. Due to the difference in surface energy within the channel, the aqueous stream is stabilized near a hydrogel and the oil stream is stabilized near the thiolene based optical adhesive defining the opposing length of the channel. Passive separation with co-laminar flow has shown success in continuously separating calcium-alginatecapsules from an oil phase into an aqueous phase. In addition to successful formation and separation of calcium alginate capsules,encapsulation of Latex micro-beads and viable mammalian cells has been achieved. The viability of encapsulated mammalian cells was determined using a live/dead stain. The co-laminar flow device has also been demonstrated as a means of separating liquid-liquidemulsions.

▼ Abstract Isobaric (200 MPa) experiments have been performed to investigate the effects of H2O alone or in combination with P, S, F or Cl on the phase relations and elemental and oxygen isotopic partitioning between immiscible silicate melts in the systems Fe2SiO4-Fe3O4-KAlSi2O6-SiO2, Fe3O4-KAlSi2O6-SiO2 and Fe3O4-Fe2O3-KAlSi2O6-SiO2 +/- plagioclase (An50). Experiments were heated in a newly-designed rapid-quench internally-heated pressure vessel at 1075, 1150 or 1200 °C for 2 hours. Water alone or in combination with P, S, or F significantly increases the temperature and composition range of two-liquid fields at fO2= NNO and MH buffers. Water-induced suppression of liquidus temperatures, considered with the effects of pressure on two-liquid fields stability in silicate melts, suggests that liquid phase separation may occur in some volatile-rich silicate magmas at pressures up to 2GPa. Two-liquid partition coefficients for Fe, Si, P and S correlate well with the degree of polymerization of the SiO2-rich conjugate melts and the data can be applied to assess the involvement of liquid-phase separation in the genesis of coexisting volatile-rich magmas. The partitioning of trace concentrations of selected HFSE, REE and transition elements between immiscible experimental volatile-rich melts at 1200 °C, 200 MPa has been determined at QFM, NNO and MH oxygen buffers. Water generally increases the partitioning of HFSE, REE and transition elements into the Fe-rich melt. Water alone, or combined with P or S, produces nearly parallel partitioning trends for HFSE and REE. Absolute partitioning values of transition elements are strongly dependent on the network-modifier composition of the melt. 18O in experimental immiscible melts with H2O or H2O and P or S partitions preferentially into the felsic conjugate melt (δ18O felsic melt- δ18O mafic melt values range from 0.4 to 0.8 permil) consistent with observations in anhydrous immiscible silicate melts. The expansion of the P-T-X-fO2 stability ranges of two- or three-liquid fields observed in the experimental melts demonstrates that liquid-immiscibility may be an important process in the evolution of some volatile-rich natural magmas. The results support an immiscible petrogenetic origin for some iron-oxide dominated, Kiruna-type, ore-deposits.

▼ The origin of tourmaline nodules, bizarre spherical to irregular textures documented worldwide, remains a geologic mystery. Although previously described by numerous researchers, the physical and chemical parameters that govern their formation have yet to be resolved. Commonly containing tourmaline, quartz, and occasionally feldspar, nodules are surrounded by a halo of leucocratic host rock, and are typically eight to ten centimeters in diameter. Tourmaline nodules of the present study are contained within the Paleoproterozoic Scrubber Granite of the southern Gascoyne Complex in Western Australia. This study integrated field observations, nodule petrography, tourmaline crystal chemistry, tourmaline fluid inclusion analyses, whole rock chemistry of nodule cores, leucocratic halo zones and host granite zones, stable and radiogenic isotope signatures of tourmaline separates as well as comparisons with other tourmaline nodule studies to propose the most scientifically sound theory for the formation of tourmaline nodules in the Scrubber Granite. Numerous nodule morphologies, including spherical and C-shaped nodules, along with other features such as tube-like nodules and tourmaline veins occur in massive, porphyritic, foliated and sheared phases of the Scrubber Granite. Microscopically, tourmaline displays prismatic, sub-rounded and massive textures. Microthermometric studies completed on tourmaline fluid inclusions revealed that the nodule-forming fluid contained 14 to 15 weight percent NaCl + CaCl2. Based on stable isotope studies and homogenization temperatures, fluid temperatures were constrained between 450 and 700¢ªC. The ¥ä18O and ¥äD concentrations of the nodule-forming fluid at this temperature range plot above the typical magmatic water field. Epsilon Nd values indicate that the tourmaline nodules of the Scrubber Granite may have been disturbed by a later metamorphic event.Tourmaline nodules of the Scrubber Granite are herein proposed to have formed from the exsolution and rise of buoyant pockets or bubbles of volatile fluid derived from the crystallizing Scrubber Granite magma.

The separation of distilled water and coconut fatty acid (CNFA) was investigated in a 4 in. x 16 in. vertical gravity decanter to determine the most significant design variables. The design variables studied were tangential versus perpendicular feed flow, height/diameter ratio, the total feed flow rate, the temperature and the intertace position with respect to feed inlet. The criteria used were the calculated immiscible concentration of water in CNFA overflow (Cw) and that of CNFA in water underflow (Co), The test conditions were arranged according to a Central Composite Design based on Box Method of Experimentation. Two levels of inlet geometry and five levels of each of the other four variables were studied. The range of variables were 1. Inlet geometry Tangential and Perpendicular Feed Flow 2. Height/Diameter Ratio 3/1 to 4/1 3· Total Feed Flow rate 160 cc/min. to 320 cc/min. 4. Temperature 40° to 80°c. 5· Interrace Position 2" below feed inlet to 2" above feed inlet The Overall residence time in the decanter ranged from 7.5 to 12.5 minutes. The drop size distribution of the incoming dispersion was measured by taking photomicrographs for all the runs. It was found that the tangential feed flow was slightly better but not significantly better for the separation of two immiscible liquids. Statistical analysis revealed that 95% confidence level height/diameter ratio, flow rate and temperature, respectively, are the most important design variables for the separation of CNFA from water underflow. The dependence of Cw on height/diameter ratio of Co on the interface position was interpreted to mean that the theoretical, plug flow residence time within each phase is the most important design variable. Interaction between variables and second order constants were not found significant at 95% confidence level. Sedimentation rather than coalescence appeared to be the controlling factor in the present study.

▼ An important unsolved problem in the study of ion distributions is the relationship of macroscopic electrochemistry measurements to the ion distribution determined by microscopic synchrotron x-ray scattering measurements. In this work, we present recent x-ray reflectivity and interfacial tension measurements of electrified oil/water interfaces as a function of interfacial electric potential for a series of interfaces between solutions of 10 mM alkali chloride (XCl, where X is the alkali metal ion of Li+, Na+, Rb+ and Cs+) in water and 5 mM organic supporting electrolyte BTPPATPFB in 1,2-dichloroethane. The potential is established by the use of electrodes and supporting electrolytes in the bulk phases. The impedance spectroscopy as a function of interfacial electric potential was also measured for each interface. The analysis of interfacial tension and impedance spectroscopy measurements were discussed and compared with the results from x-ray reflectivity analysis as well. Cyclic voltammogram was measured for each interface to determine the working potential range. Interfacial tension measurements were performed using a Cahn microbalance that measures the weight of a Teflon Wilhelmy plate fully submerged in the top water phase to determine the potential of zero charge (PZC) and the capillary wave roughness of the interfaces. The interfacial excess charge as a function of electric potential was determined from the tension measurements. Impedance spectroscopy was measured for each interface to determine the capacitance as a function of applied electric potentials. X-ray scattering experiments were carried out at the ChemMatCARS beamline 15-ID at the Advanced Photon Source (Argonne National Laboratory, USA). Large changes in reflectivity occur from intermediate potentials for each sample we study. These results disagree with predictions of the Gouy-Chapman (GC) theory. A Poisson-Boltzmann (PB) calculation that incorporates a potential of mean force (PMF) to describe the role of liquid structure on the ion distributions agrees well with the x-ray reflectivity data. In addition, we calculated the excess interfacial charge from these ion distributions. These calculated excess interfacial charges from the PB-PMF method are in good agreement with the tension measurement results. We also calculated the capacitance as a function of applied electric potentials for each sample from the PB-PMF calculations, and these results only showed limited agreements with the capacitance yielded from the impedance spectroscopy measurements. These comparisons make a direct connection between the molecular level x-ray measurements and macroscopic electrochemistry measurements of interfacial tension and impedance spectroscopy.
