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...

A technique for spatially resolved wall temperature measurements in microchannel heat sinks using infrared thermography

Creator:: Krebs, Daniel P.
Abstract:: A non-intrusive measurement technique for direct quantitative thermal visualization of channel wall temperatures in two phase microchannel flows using infrared thermography (IRT) is presented. Specifically, the measurement of top channel wall temperatures in a fractal-like branching microchannel silicon heat sink during flow boiling is demonstrated and thoroughly documented. Obtaining quantitative...

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...

Numerical simulation of micro/mini-channel based methane-steam reformer

Creator:: Peterson, Daniel Alan
Abstract:: Numerical modeling of methane-steam reforming is performed in a micro/mini-channel with heat input through catalytic channel walls. The low-Mach number, variable density Navier-Stokes equations together with multicomponent reactions are solved using a parallel numerical framework. Methane-steam reforming is modeled by three reduced-order reactions occurring on the reactor walls. The surface...

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...

Making the Unconscious Unconscious : Reclaiming Microinteractions for People with Motor Disabilities

Creator:: Lazewatsky, Daniel A.
Abstract:: Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...

Fluidic and thermal modeling for the high production rate synthesis of high quality nanoparticles

Creator:: Peterson, Daniel Alan
Abstract:: Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...

Model Predictive Control for Underwater Robots in Ocean Waves

Creator:: Fernández, Daniel C.
Abstract:: Underwater robots beneath ocean waves can benefit from feedforward control to reduce position error. This thesis proposes a method using Model Predictive Control (MPC) to predict and counteract future disturbances from an ocean wave field. The MPC state estimator employs a Linear Wave Theory (LWT) solver to approximate the component...

Experiments on a low aspect ratio wing at low Reynolds numbers

Creator:: Morse, Daniel R.
Abstract:: At the start of the 21st century much of the focus of aircraft design has been turned to unmanned aerial vehicles (UAVs) which generally operate at much lower speeds in higher risk areas than manned aircraft. One subset of UAVs are Micro Air Vehicles (MAVs) which usually are no larger...

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...
