Flow Regime-Independent Two-Group Interfacial Area Concentration Model For Dispersed Gas-Liquid Flows In Large-Diameter Pipes, Hossein Barati, Takashi Hibiki, Joshua P. Schlegel, Naofumi Tsukamoto

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

In many power plants, boiling can result in two-phase flows during normal and accident conditions. Heat and mass transfers through the gas-liquid interface in a two-phase flow process are proportional to the interfacial area concentration (IAC). These calculations for nuclear systems are typically performed using advanced system analysis codes such as TRACE. TRACE uses a two-group (2G) model, where bubbles are divided into two groups according to their drag coefficients. Correlations are used to calculate the group-wise void fractions (VFs) and IACs. This study evaluates the accuracy of the TRACE 2G VF and IAC models for vertically upward dispersed flows …

Implementation Of Tritium Transport In A Gas-Liquid Contactor Cfd Simulation Of Tritium Extraction From Lead-Lithium In Ansys Fluent, Anthony G. Bowers, Subash L. Sharma, Thomas F. Fuerst

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

Modifications to the Computational Fluid Dynamic (CFD) software ANSYS Fluent were done to quantify and characterize tritium transport in gas-liquid contactors (GLCs). A double-slit, Ergun-like equation was employed for the porous media model, with Ergun coefficients validated with Sulzer's Sulcol software. Tritium transport from PbLi within the GLC was verified against analytical models. The geometry of the CFD model was based on the MELODIE GLC experiment. The hydrodynamic CFD pressure drop results align well with Sulcol estimations and fall between the predictions of the analytical Delft-Olujić and Billet and Schultes models. In terms of mass transfer efficiency, traditional mass transfer …

Synthesis Of Nickel Nanoparticles By Gamma Irradiation And Femtosecond Laser Ablation, V. M. Rao, Y. Han, H. Tsai, C. H.C. Giraldo, T. Akyurek

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

Nickel nanoparticles were synthesized by (i) gamma irradiation of aqueous nickel chloride precursors and (ii) double scan femtosecond laser (FSL) ablation of a pure nickel foil in water. The nanoparticles produced by FSL ablation were further stabilized in acetone. Gamma radiolysis yielded nickel nanoparticles in the 2–22 nm range, with the average particle diameter governed by the total absorbed dose. Nickel nanoparticles produced by double scan FSL ablation were in the 2–17 nm range but less monodispersed than the nanoparticles produced via gamma radiolysis. FSL ablation proved to be superior in terms of yielding a higher number of smaller nanoparticles …

Inside Out: Improving Large Model Safety, Wei Zhao

Dissertations and Theses Collection (Open Access)

While Large Language Models (LLMs) and Multimodal Large Language Models (MLLMs) are at the frontier of current advancements in artificial intelligence, demonstrating remarkable capabilities across diverse applications, there are growing concerns about their reliability and security. LLMs remain vulnerable to adversarial attacks through carefully crafted prompts that circumvent safety mechanisms, while MLLMs face additional security challenges stemming from their multimodal nature. Despite considerable efforts in reinforcement learning from human feedback (RLHF) and supervised fine-tuning, existing safeguards have proven inadequate in addressing these critical vulnerabilities. This inadequacy stems from the fact that these models are inherently blackboxes that do not provide …

The Impact Of Corporate Mergers And Acquisitions On Performance From The Perspective Of Growth Pressure, Jiandong Wang

Dissertations and Theses Collection (Open Access)

Against the backdrop of economic volatility and intensified industry competition, firms generally face multidimensional growth pressures, including historical growth pressure, social growth pressure, and market competition pressure. Growth pressure is not only related to firms’ operational stability, but also profoundly influences their strategic choices, particularly merger and acquisition (M&A) behaviour.Grounded in performance feedback theory, this study constructs an integrated analytical framework encompassing growth pressure, M&A strategic decisions, and M&A performance, and systematically examines how different types of growth pressure affect firms’ M&A decisions, as well as how M&A performance varies across different firm characteristics and different types of M&A.

Improving Evacuation Effectiveness On Cruise And Large Passenger Ships : An Analysis Of Human Factors, Safety Culture, And Behavioral Dynamics, Antonios Andreadakis

World Maritime University Ph.D. Dissertations

Maritime trade has long constituted a central pillar of economic development, supporting global commerce and cultural exchange. Nevertheless, the maritime environment is inherently hazardous and therefore the protection of human life has consistently constituted and will continue to remain a central priority (Casson, 1995). An instrumental turning point in maritime safety occurred after the sinking of Titanic in 1912, which prompted in 1914 an International Conference dedicated to the protection of human life at sea; which ultimately led to the adoption of the International Convention on Safety of Life at Sea (SOLAS) (Dalaklis, 2017). This Convention introduced internationally imposed safety …

Fluid Dynamics Of A Microfluidic Micromixer–Micropump Driven By Adjacent Micro Synthetic Jets, Delara Soltani, Tim Persoons, Sajad Alimohammadi

Research Outputs: 2025-Present

Efficient mixing at the microscale remains a significant challenge in microfluidic systems due to the dominance of laminar flow and the consequent limitation of convective transport. Synthetic jets, generated by the oscillatory motion of a diaphragm within a cavity, produce a zero net mass flux while imparting periodic momentum to the surrounding fluid, thereby enabling localised flow perturbation and vortex generation that can substantially enhance mixing and mass transfer in microchannels. In this study, a pair of adjacent micro synthetic jets (AMSJs) is positioned perpendicularly to a microchannel to investigate their potential as a novel micropump-mixer. The vectoring effect of …

A Simplified Computational Fluid Dynamics Investigation Of Internal Duct As A Passive Aerodynamic Solution For Electric Trucks, Omar K. Omar, Ahmad Abu Shanab, Mohammad Tarawneh, Sara Hawarneh, Dr Hani Alkhatib

Research Outputs: 2025-Present

Aerodynamic drag is a dominant factor affecting the efficiency and driving range of electric trucks, especially at high speeds. Although previous studies have mainly focused on external drag-reduction devices, internal airflow control strategies such as integrated ducts have received limited attention. This study addresses that gap by analyzing how placing an internal duct in the truck body affects drag and power efficiency. A simplified two-dimensional computational fluid dynamics (CFD) approach was employed using ANSYS Fluent to evaluate and compare a baseline truck model and a modified configuration featuring a central internal duct. The simulations assessed the drag coefficient, drag force, …

Water-Efficient Concrete Curing Using Sap-Infused Nonwoven Blankets: Material Screening And Performance Evaluation, Feras Kafiah, Omar K. Omar, Dr Hani Alkhatib

Research Outputs: 2025-Present

Concrete curing under hot-weather exposure requires sustained surface moisture while minimizing repeated waterapplication. This study develops and evaluates a two-layer external curing blanket comprising a polyethylene (PE) top sheetand a superabsorbent polymer (SAP)-infused needle-punched nonwoven polyester layer. Ten PE sheets, three sodiumpolyacrylate SAP grades, and three nonwoven fabrics were screened sequentially according to optical transmittance, SAPmorphology and absorption behavior, fabric absorptivity, SAP-fiber integration, and qualitative seven-day surface-wetnessobservations. The selected configuration (S7 PE/SAP 3/GT-80) was then demonstrated using a 1 × 2 m2 outdoor prototypeand compared with conventional wet burlap curing. The blanket-cured concrete produced a numerical mean core strengthof 36.5 …

The One Big Beautiful Big Act (OBBBA) of 2025 is generally consideredto be a continuation of the Tax Cuts and Jobs Act (TCJA) of 2017.1Thatis definitely true as far as the individual tax provisions are concerned, be-cause the OBBBA merely made permanent the TCJA provisions with minorchanges, such as increasing the cap on the state and local tax deduction from$10,000 to $40,000. For the corporate tax, the OBBBA continued some of thechanges in the TCJA (such as expensing) while relaxing others (such as amorti-zation of research and experimentation (R&E) expenditures and a stricter limiton interest deductions) without changing the overall …

Crypto Kleptocracy, W. Robert Thomas, Jeffery Y. Zhang

Michigan Law Review Online

Many Americans are worrying about whether they will soon be living in a postdemocracy autocracy. But in the meantime, they may already be living in a crypto-fueled kleptocracy. Less than one year into his second presidential term, Donald Trump has reportedly taken his wealth to new heights by embracing, both as a businessman and a politician, the crypto industry. Trump’s family businesses are involved in minting Trump-themed meme coins, creating America- themed stablecoins, and mining crypto assets—so successfully that most of Trump’s wealth is likely now from crypto, not real estate. All the while, the Trump Administration is rolling back …
