Investigation of Thermal Degradation in Structural Alloys for Nuclear Power Systems

Creator:: Teng, Fei
Abstract:: The thermal degradation of structural materials is considered to be a key factor for evaluating the lifetime of current nuclear power plants. Ni-based and Fe-based alloys, such as 690, 625, 304, and 316, are widely used in nuclear industry as structural components due to the extraordinary corrosion resistance and mechanical...

Determination of Mass Flow Rate through Plain Mesh Wick and Nano- Structured Mesh Wick for the Design of Thermal Compressor Systems

Creator:: Uwaoma, Ifeanyi A.
Abstract:: Wicking action refers to the movement of a liquid through a porous or a structured surface via capillary action. This phenomenon is affected by surface geometry, such as the wick thickness and pore size of the wick, as well as fluid properties, such as viscosity and surface tension of the...

Template-based control of the bipedal robot ATRIAS

Creator:: Peekema, Andrew T.
Abstract:: This thesis details the derivation and application of template-based controls on a bipedal robot, as well as a description of the software framework that enabled experimentation. The software framework uses a combination of open-source tools including ROS, OROCOS, EtherCAT, and Xenomai to create a real-time environment for the controllers. The...

Development and Application of a Reduced Chemical Kinetics Model for Low-Speed Pre-Ignition Investigation

Creator:: Tran, Khang NV.
Abstract:: Gasoline direct injection engines, with downsized boosted technology, present a promising option for enhancing power density and reducing fuel consumption for next-generation engine designs to meet stringent fuel economy and emission standards. However, these developments in the low-speed and high-load operating regime are challenged by the occurrence of a new...

Assessing Mass Diffusion Modeling in Premixed Flames

Creator:: Fillo, Aaron J.
Abstract:: Implementing multicomponent diffusion in numerical combustion studies is computationally expensive due to the challenges involved in computing diffusion coefficients. As a result, mixture-averaged diffusion treatments or simpler methods are used to avoid these costs. However, the accuracy and appropriateness of the mixture-averaged diffusion model has not been verified for three-dimensional...

Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

Creator:: Mayer, Morgan A.
Abstract:: High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

Influences of Replacing Cr with Mo in Fe25Co25Ni25Cr25-XMoX High Entropy Alloy Series on the Microstructure and Mechanical Properties

Creator:: Xu, Yifan
Abstract:: Fe25Co25Ni25Cr25-XMoX High Entropy Alloys were fabricated in mini arc-melter and then cast into 4mm diameter cylinders by injection casting technique and 1cm diameter cylinders by water quenching technique. Heat transfer modeling during solidification of FeCoNiCr HEA was simulated. Combining X-Ray Diffraction, Optical Microscopy, Scanning Electron Microscope, Energy Dispersive X-ray analysis,...

Passive dynamics and their influence on performance of physical interaction tasks

Creator:: Kemper, Kevin C., II
Abstract:: For robotic manipulation tasks in uncertain environments, research typically revolves around developing the best possible software control strategy. However, the passive dynamics of the mechanical system, including inertia, stiffness, damping and torque limits, often impose performance limitations that cannot be overcome with software control. Discussions about the passive dynamics are...

Hydrodynamics of droplet impingement on heated surfaces : effects of nanofluid and nano-structured surface

Creator:: Shen, Jian
Abstract:: This study investigates the hydrodynamic characteristics of droplet impinging on heated surfaces using High Speed High Resolution (HSHR) imaging and evaluates the effect of surface temperature and using water and a nanofluid on a polished and a nano-structured surface. Three types of surfaces are used in the study: polished silicon,...
