  • Finite volume method modeling of corona discharge microreactor oxidization of dibenzothiophene

    Creator:
    Fan, Xiangru
    Abstract:
    The growing need for cleaner fuels requires the development of better deep fuel desulfurization methods. The current study presents a reaction model for the mechanism of dibenzothiophene oxidization by dissolved oxygen occurring in a corona discharge microreactor. In the present work, a Finite Volume Method model of the reactor is...

  • Prediction of mass transfer performance of microchannel dialyzersusing deconvolution of impulse-response experiments

    Creator:
    Anderson, Eric K.
    Abstract:
    The parallel implementation of a large number of functional units is necessary for any industrial scale microfluidic process. The concept of a 'numbering up' strategy where a single highly optimized functional unit that has a low individual production is replicated a large number of times to create a device that...

  • Numerical Modeling of Mass Timber Connections

    Creator:
    Hollenbeck, Sean R.
    Abstract:
    Cross-Laminated Timber (CLT) is a prefabricated building material that is relatively new to the United States and North America. It consists of no less than three layers of graded, dimensional lumber glued in alternating longitudinal and transverse layers to create a panel that can be used for various building applications...

  • Compatible Discretizations for Maxwell's Equations with General Constitutive Laws

    Creator:
    McGregor, D. A.
    Abstract:
    In this thesis we construct compatible discretizations of Maxwell's equations. We use the term compatible to describe numerical methods for Maxwell's equations which obey many properties of vector Calculus in a discrete setting. Compatible discretizations preserve the exterior Calculus ensuring that the divergence of the curl and the curl of...

  • Coastal Soil and Structure Behavior during Earthquake-Tsunami Multi-Hazards

    Creator:
    Qiu, Yingqing
    Abstract:
    Coastal multi-hazards, i.e., earthquakes followed by tsunamis, induce severe damage to coastal infrastructure. The multi-hazards can cause soil liquefaction, which is one of the major concerns for evaluating sediments transport potential and structure failure mechanisms. The objectives for this work is threefold. First, to build and validate a soil numerical...

  • Finite element transport using Wachspress rational basis functions on quadrilaterals in diffusive regions

    Creator:
    Davidson, Gregory G.
    Abstract:
    Wachspress rational functions are ratios of polynomials having certain properties which make them good candidates for basis functions in finite element methods. In addition. it had been theorized that Wachspress rational weight functions should Provide a full-resolution discretization of the neutral particle transport equation in thick diffusive regions, but this...

  • High Order Finite Elements SN Transport in X-Y Geometry on Meshes with Curved Surfaces in the Thick Diffusion Limit

    Creator:
    Woods, Douglas N.
    Abstract:
    The high-order finite element S[subscript N] transport equations are solved on several test problems to investigate the behavior of the discretization method on meshes with curved edges in X-Y geometry. Simpler problems ensured the correct implementation of MFEM, the general fi nite element library employed. A convergence study using the...

  • Fluid-structure interaction analysis with the particle finite element method

    Creator:
    Zhu, Minjie
    Abstract:
    To facilitate the evaluation and design of structures subjected to fluid loading, a study of fluid-structure interaction (FSI) using the particle finite element method (PFEM) is presented to approximate the responses and sensitivities of structures which interact with fluid. A wide range of structural types are permissible by making no...

  • Evaluation of finite element techniques for soil reinforcement applications

    Creator:
    Berg, Ryan Robert
    Abstract:
    A literature review and a computer study are conducted to identify the requirements of finite element programs for the specific use of discrete analyses of reinforced soil structures. The utility of six commercially available programs are appraised with respect to the identified requirements. The results of the study are directed...

  • Nonlinear solvers for a model problem of fluid flow in the subsurface

    Creator:
    Biederman, Shannon Miriah
    Abstract:
    Water is one of the most biologically and economically important substances on Earth. A significant portion of Earth's water subsists in the subsurface. Our ability to monitor the flow and transport of water and other fluids through this unseen environment is crucial for a myriad of reasons. One difficulty we...
