CFD simulation of single-phase and flow boiling in confined jet impingement with in-situ vapor extraction using two kinds of multiphase models

Creator:: He, Xiaoliang
Abstract:: With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...

Mechanics of three-dimensional microenvironments of cells

Creator:: Jones, Christopher
Abstract:: The structure and mechanics of tissues affect many important cellular functions such as migration, differentiation, and growth. Mechanical interactions between cells and the extracellular matrix (ECM), as well as ECM-mediated mechanical communication between cells, plays a part in coordinating collective cellular dy- namics during critical processes such as morphogenesis, tissue...

Solution-based deposition of functional thin films : development of a glucose biosensor and thermal processing of CZTS nanoparticle films

Creator:: Durgan, Christopher J.
Abstract:: The development of solution-based methods for deposition of different thin film material is presented as an alternative to high cost vacuum-based methods. For certain materials, vacuum techniques are unsuitable for processing. Additionally, vacuum-based processes present high capital costs associated with equipment, and slow processing times. Atmospheric pressure solution based techniques...

Steady State Modeling of the Minimum Critical Core of the Transient Reactor Test Facility

Creator:: Alberti, Anthony L.
Abstract:: With the advent of next generation reactor systems and new fuel designs, the U.S. Department of Energy (DOE) has identified the need for the resumption of transient testing of nuclear fuels. The DOE has decided that the Transient Reactor Test Facility (TREAT) at Idaho National Laboratory (INL) is best suited...

Investigation of In-tube Non-equilibrium Condensation of Low Global Warming Potential Refrigerants

Creator:: Jacob, Tabeel A.
Abstract:: This work investigates the in-tube condensation of low global warming potential (GWP) zeotropic refrigerant mixtures R448A, R450A, R452A, R454B and R454C. These refrigerants have been proposed for a wide range of commercial heating, ventilation, air-conditioning applications, but their heat and momentum transport phenomenon were not well understood. Thus, in this...

A Computational Investigation of Natural Circulation Effects on Heat Transfer Coefficient and Friction Factor

Creator:: Buskirk, John
Abstract:: The nuclear industry has shown a large interest in natural circulation driven passive cooling systems following the Fukushima nuclear accident. Despite this interest, there is no widely used heat transfer correlation or friction factor correlation developed for natural circulation driven flow. A CFD analysis including grid convergence testing using Fluent...

Investigating the Effect of Tetrahydrofuran (THF) Plasticizer on the Crystallization and Solvent Seaming of PET/NPG Copolymer Films

Creator:: Srivastava, Aarushi
Abstract:: Polyethylene terephthalate (PET) polymer has been the material of choice for packaging industry as a result of its excellent mechanical and physical properties. These properties are highly dependent on the microstructure, chemistry, and processing conditions of this material. PET is often oriented in the machine direction (MD), the transverse direction...

External Coupling of Computational Fluid Dynamics Modeling of the Density Evolution Inside of the Helium-3 Enhanced Negative Reactivity Insertion (HENRI) System with the Monte-Carlo Neutronics code Serpent 2

Creator:: Leingang, Cole W.
Abstract:: The testing of nuclear fuel under reactivity-initiated accident (RIA) conditions is paramount for the better understanding of the fuel’s behavior during these transient accident events. The Transient Reactor Test (TREAT) facility is a nuclear reactor that will be capable of recreating the thermal-hydraulic and neutronic boundary conditions representative of RIA...
