Multi-Stage Electrolysis for Reduction of Electricity Consumption in Hydrogen Production
A novel approach to perform electrolysis in stages is developed for reducing the share of electric work in the process and replacing the same with thermal energy. The study is divided into two parts, the first part is a ... -
Simulations and validation of an axial-flow pit turbine
The geometric design of an axial-flow pit-turbine is essential as flow separation will decrease turbine efficiency. In this thesis, steady Reynolds Averaged Navier Stokes (RANS) simulations were conducted with a two-equation ... -
Vibroacoustic Analysis and Optimization of an Aft-Fuselage Mounted Twin-Engine Aircraft
Aft-fuselage mounted twin-engine style aircraft dominate the business jet industry. This aircraft provides a decreased transmission path for structure-borne engine vibrations when compared to wing-mounted aircraft found ... -
Development of Large-Scale Particle Tracking Velocimetry: A Comparison Between 2D and 3D Techniques
This study compares the three-dimensional version of a previously proposed large-scale particle tracking velocimetry (LS-PTV) measurement system with a simpler, less computationally expensive, two-dimensional version for ... -
Separated Flows Over Non-slender Delta Wings
Wings with sweep are ubiquitous for engineering applications, and are observed in biology for swimmers and fliers alike. In particular, delta wings have wide ranging applicability arising from their low speed maneuvering ... -
Electrification of home heating in Ontario with the air-source heat pump
Home heating is the primary energy end-use in Ontario homes. Consequently, it is also the largest source of greenhouse gas emissions in the residential sector, particularly because most homes in Ontario use fossil fuels ... -
Electromagnetically Navigated Forearm Fracture Plating
Electromagnetic (EM) tracking is currently a feasible tracking modality to navigated surgical operations on delicate bone structures, but how accurate and consistent could the navigation be in the case of forearm fracture ... -
Multi-Material and Multi-Joint Topology Optimization of 3D Structures
In recent years, topology optimization has become a popular tool in automotive, aerospace and defense industries to generate novel clean slate designs. The most modern of these tools is multi-material topology optimization ... -
Characterization of Strain Rate Sensitivity, Plastic Anisotropy, and Dislocation Content in Zircaloy-2
Zirconium alloys are used broadly throughout the nuclear industry due to a combination of its mechanical properties, low neutron absorption cross section, and resistance to corrosion. Understanding the process of plastic ... -
Mode I Fracture Testing on Zirconium Foils Under Plane-stress Condition
Zirconium alloys are commonly used in nuclear reactor in-core components due to their good mechanical properties and low neutron-absorption cross-section. Especially for CANada Deuterium Uranium (CANDU) reactors, zirconium ... -
Optical Visualization of Two Phase Flow in PEM Electrolyzers
Polymer electrolyte membrane (PEM) electrolyzers are ideally suited to pairing with renewable energy sources given the capability to operate at high current densities and transition between different potential loading. ... -
Design of Uniformly Textured Polymer Surfaces for Hard-soft Bearing Systems
The aim of this study is to investigate the effect of surface texturing for improving the tribological performance of metal-ultra high molecular weight polyethylene (UHMWPE) bearing systems during intermittent stop-dwell-start ... -
Finite Element Analysis of Cortical Shell Contributions to Apparent Stiffness and the Effect of Vascular Apertures in Rat Vertebrae Under Uniaxial Compression
Osteoporosis is a degenerative bone disease that causes an increase of fracture risk. The present method of diagnosing the disease is through a bone mineral density (BMD) scan which neglects bone quality. Due to the ... -
3-D Design for Additive Manufacturing Utilizing Topology Optimization
As the frontier of modern-day engineering challenges pushes forward, the integration of multiple strategies to reduce manufacturing cost and increase component performance has engineers turning to tools such as topology ... -
Deformation-Induced Phase Transformation in a Quaternary Zirconium Alloy
Zirconium alloys are used extensively in the nuclear industry, largely due to the very low neutron capture cross-section of zirconium. Alloying of zirconium with substitutional solutes, like Sn, Mo or Nb, is common to ... -
Characterization and modeling of near-field BLEVE overpressure and ground loading hazards
Boiling Liquid Exploding Vapor Explosion (BLEVE) is one of the most feared accident in the industry. Even though it has been studied for over 6 decades, many safety questions remain poorly answered: what happens if a BLEVE ... -
Multi-material topology optimization for lightweight design
Multi-material topology optimization remains an active research topic. This work enriches the key techniques of multi-material topology optimization, such as the multi-material property determination, topology optimization ... -
Effects of Microstructure and Particle Population on Void Damage Evolution in Complex Phase Steel
This thesis aims to provide a detailed description of the microstructure and void damage evolution in a grade of hot-rolled complex phase (CP) sheet steel produced by ArcelorMittal Dofasco (AMD). The evolution of ... -
Modelling and Transient Simulation of Solar-powered Hydrogen Energy Storage Systems
Practical energy storage systems are essential for matching the intermittent production of renewable power sources with the time dependent power demand of residences and businesses. This study assesses the technical viability ... -
Methods for Improving Ability to Investigate the Effectiveness of Non-Invasive Treatment Strategies for Medial Knee OA
Osteoarthritis (OA) is the most common form of arthritis, occurring frequently in the medial compartment of the knee. As the onset and progression of medial knee OA has been associated with abnormal and excessive loading ...
