A Computational Framework for Resilience-Informed Design

Creator:: Hulse, Daniel E.
Abstract:: It is desirable for complex engineered systems to perform missions efficiently and economically, even when these missions' complex, variable, long-term operational profiles make it likely for hazards to arise. It is thus important to design these systems to be resilient so that they will actively prevent and recover from hazards...

Power performance of planing boats with the effect of propeller selection and propeller guard design

Creator:: Ladd, Daniel M.
Abstract:: One of the unique problems associated with salmon gillnet fishing is of preventing the fouling of the boat's propeller in the net and associated fishing gear. Presently, the solution to this problem has been the addition of a basket type propeller guard which may produce a drag increase of 50...

A study of adiabatic and diabatic flow boiling in parallel microchannels and fractal-like branching microchannels

Creator:: Daniels, Brian J.
Abstract:: A one-dimensional numerical model has been developed to study diabatic and adiabatic flow boiling in microchannels. This model accounts for developing flow effects and variable property effects. The model uses correlations for void fraction and two-phase multipliers found in the literature. The model has been used to study the performance...

Swept time-space domain decomposition on GPUs and heterogeneous computing systems

Creator:: Magee, Daniel J.
Abstract:: Modern scientific and engineering problems often require simulations with a level of resolution difficult to achieve in reasonable amounts of time—even in effectively parallelized programs. Therefore, applications that exploit high performance computing (HPC) systems have become invaluable in academia and industry over the past two decades. Addressing the questions that...

Functional imaging reveals modest strain concentrations associated with implant micromotion using modified BAK interbody cages

Creator:: Berry, Daniel J.
Abstract:: Interbody fusion cages are increasingly used in the treatment of spinal disease and injury in order to stabilize movement and promote arthrodesis of the vertebral bodies, but the micro-mechanics of the interaction between the cage and the adjacent host bone is not fully understood. This information has bearing on post-surgical...

A study of the characteristics of oscillatory surface instabilities leading to droplet formation

Creator:: Daniels, Brian J.
Abstract:: The characteristics of the free surface in an orifice driven by a periodic forcing function have been studied both theoretically and experimentally. In the theoretical study, two wall boundary condition cases were examined: 1) the radial velocity at the wall of the orifice is zero; and 2) the axial velocity...

Describing Tsunami Inundation and Debris Motion using Optical Measurement Methods in a Large-Scale Wave Basin

Creator:: Rueben, Matthew Robert
Abstract:: This thesis consists of two papers in manuscript format. The first paper presents optical measurements of tsunami inundation through an urban waterfront in a laboratory wave basin. The physical model was constructed at 1:50 scale and was an idealization of the town of Seaside, Oregon. The paper presents an analysis...

Experimental Classification of Intralaminar Matrix Compression Damage Propagation in Carbon Fiber Reinforced Polymers

Creator:: Daniels, Mitchell Alan
Abstract:: Composites often are able to carry more load after damage due to the structure of laminates. In addition, damage can be difficult to detect in composites compared to homogeneous materials. Understanding the behavior of composite material after damage is vital for composite structural design. Currently, experimental methods exist for classifying...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

The effect of geometric orientation and random wind conditions on flat plate convection rates

Creator:: Melchior, Daniel K.
Abstract:: An experimental investigation has been performed to determine the forced convection heat transfer due to three-dimensional air flow over a flat plate as a function of angle of attack and free stream velocity. The experimental method employed a transient thermal technique and placed the convecting surface next to the exhaust...
