Image Theses and Dissertations Analysis of Micromixers on Reverse Osmosis Based Desalination Membranes Corrugated membranes are used in desalination modules to improve membrane performance. In this study, in order to gain a deeper insight into the separation performance of these corrugated membranes, a computational fluid dynamics simulation was carried out for a proposed three-dimensional desalination modules containing triangular and square ribs attached to the membrane surface.

Image Theses and Dissertations Coarse Grain Molecular Model Development and Implementation for Describing von Willebrand Factor Behavior in Human Blood Flow von Willebrand Factor (VWF) is a large multimeric protein which is very important for the hemostasis of bleeding blood vessels. Critical steps in the process are the accumulation and aggregation of platelets at the damaged vessel wall, forming hemostatic plugs. Near injury sites, hydrodynamic force in the bloodstream elongates VWF with a sharp increase, exposing binding sites for platelets and collagen. View Item
Image Theses and Dissertations Packed Bed Reactor Design For High Temperature Thermochemical Energy Storage Using Metal Oxide Redox Reaction Themochemmical energy storage (TCES) compared to other energy storage solution is more suitable due to possibility of storage at higher density and even higher temperatures. Thermal energy is stored/released using a reversible endothermic/exothermic reaction. For large-scale high temperature heat storage, TCES in nearly the only solution compared to the sensible or latent heat storage. However, high temperature TCES is at research stage and has not been commercialized yet. View Item

Image Theses and Dissertations Gas Seperation through Hollow Fiber and Spiral Wound Membranes Computational fluid dynamics simulations are conducted for multicomponent fluid flows over banks of hollow fiber membranes. The hollow fiber membrane systems is considered here for gas separation applications. Separation of carbon dioxide (CO2) from methane (CH4) is studied using hollow fiber membranes packed in different arrangements. The membrane surface is considered as a functional surface where the mass flux and concentration of each species are coupled and are determined as a function of the local partial pressures, the permeability, and the selectivity of the membrane.

Image Theses and Dissertations Mitigation of Flow-Induced Pressure Fluctuations Inside a Francis Turbine Using Large Eddy Simulations Computational fluid dynamics simulations were conducted to study the performance of a Francis turbine operating at various flow rates spanning from ultra-low to excessive load. Francis turbine used in this study is rated at an industrial size of 1MW. High-fidelity large eddy simulations (LES) were utilized to characterize the cavitating turbulent flow structures inside the turbine unit. The axial, peripheral, and tangential water injections from the runner crown center and draft tube wall are considered to stabilize the turbine operation. View Item
