Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

Creator:: Bowen, Michael S.
Abstract:: Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

Sensitivity of Hashin damage parameters for notched composite panels in tension and out-of-plane bending

Creator:: Wright, Thomas J.
Abstract:: When using Finite Element Analysis (FEA) to model notched composite panels, the values of certain material properties can have a great effect on the outcome of the simulation. Progressive damage modeling is used to model how a composite structure will fail, and how that failure will affect the response of...

Temperature Evolution of Spark Kernels in Quiescent and Cross-flow Conditions

Creator:: Okhovat, Sebastian
Abstract:: Numerous physical and chemical processes are required for successful ignition of a flammable mixture, many of which have been well characterized. However, one aspect of the ignition process that has received limited consideration is understanding the temperature of the spark kernel. A spark kernel is the volume of heated gas...

Heat Treatment Effects on the Mechanical Properties and Microstructure of CPM-M4 Tool Steel

Creator:: Fast, Cody P.
Abstract:: Variations in heat treatments have significant effects on the microstructure of tool steels. For CPM-M4 tool steel, the changes in microstructure and mechanical properties were observed based off of variations in temperature. Five heat treatments with constant exposure time and variable austenitizing and tempering temperatures were performed on samples of...

Fatigue Testing and Analysis of Polymer and Composite Materials Used in Heavy-Duty Trucks

Creator:: Gahan, Kevan
Abstract:: As structural durability analysis is increasingly trusted during the design processes of the automotive industry, more complete and sophisticated modeling of material behavior under both static and dynamic loading conditions is paramount. This is especially true regarding the application of heavy-duty trucks, where modern designs contain large parts such as...

Implementation and evaluation of a participating media radiation model in the TEMPEST thermal-hydraulic computer code

Creator:: Rector, David R.
Abstract:: In this work, a method for solving the differential form of the radiative transfer equation was implemented into an existing three-dimensional thermal-hydraulic computer program known as TEMPEST. The method used was the P-l approximation, where the angular distribution of the radiation intensity is represented by a truncated series of spherical...

Risk-based design for multidisciplinary complex systems

Creator:: Farhangmehr, Farzaneh
Abstract:: The ultimate goal of large-scale design organizations are mainly to reduce costs and improve reliability and performance of systems while assessing how much risk (cost, schedule, scope) they can take and still remain competitive. To achieve this goal they need to develop tools to reach the most preferred design product...

A Novel Progressive Damage and Failure Analysis Model for Matrix Compression using 3D Continuum Damage Mechanics and Smoothed Particle Hydrodynamics

Creator:: Solanki, Satish
Abstract:: The matrix compression behavior is assumed similar to tension, and many material's elastic and damage parameters are considered equal in tension and compression but experimentally not explored. This assumption leads to unrealistic or very far from the actual behavior of the matrix under compression. Moreover, the pre-existing implemented Abaqus models...

Performance characterization of an integrated microscale hydrogen combustor recuperator and oil heat exchanger

Creator:: Haley, David B. (David Brien)
Abstract:: Experiments on a novel, microscale hydrogen combustor heat exchanger (µCHX) are presented in this thesis. The µCHX has been designed to efficiently transfer thermal energy to a heat transfer fluid for use in desorption of hydrogen from a metal hydride storage system of a hydrogen-powered fuel cell vehicle. The experimental...
