Optimization & Qualification of a Liquid Engine Launch Vehicle Design Using 6DoF Simulations

Creator:: Rose, Trevor J.
Abstract:: In this work, I developed a six degree of freedom flight simulator specific to liquid engine launch vehicles. This flight simulator improves upon available software by accounting for liquid engine specific phenomena such as tank pressurization, liquid engine performance, and center of gravity modeling. Additionally, I implemented methods for optimization...

Wave Energy Converter Array Optimization : Array Economic Analysis and Preliminary Results of a Genetic Algorithm Approach Introducing Cost Factors

Creator:: Sharp, Christopher J.
Abstract:: With the need to integrate renewable energy sources into the current energy portfolio and the proximity of many population centers to an ocean coastline, it is pressing that marine energy systems, specifically wave energy converters (WECs), are evaluated as potential solutions for meeting energy needs. In order to best understand...

Data-Driven Environmentally Sustainable Product Design: A Shift Toward Increased use of Sustainable Design Activities in the Early Design Phase

Creator:: Ferrero, Vincenzo J.
Abstract:: Modern product design drives the boundaries of innovation by encompassing complex Design-for-X objectives, and the inclusion of multidimensional stakeholders. This growing complexity in product design has left design teams unequipped, as classical design theory is bounded by designer experience, expertise, and cognition. One novel approach to tackling product complexity is...

Environmentally Sustainable Product Design : Understanding the Environmental Impact of Product Function and Product Labeling

Creator:: Ferrero, Vincenzo J.
Abstract:: Using repositories to store product design information can provide additional and extensive design knowledge to the global design community. Using repository data in the design of new products can be especially impactful for DfX design objectives, such as product sustainability, about which many engineering designers have limited knowledge. Furthermore, repositories...

Robustness of uncertain systems : globally optimal Lyapunov function

Creator:: Ahmadkhanlou, Fariborz
Abstract:: The Lyapunov direct method is utilized to determine the robustness bounds for nonlinear, time-variant uncertainies p[subscript i]. Determination of the robustness bounds consists of two principal steps: (i) generation of a Lyapunov function and (ii) determination of the bounds based on the generated Lyapunov function. Presently in robustness investigations, a...

Operation of a High-Temperature Oxidation Reactor for Thermochemical Energy Storage

Creator:: Ramsey, Owen C.
Abstract:: The cost of long-duration energy storage poses one of the most significant limitations on the penetration of renewables into power grids. Thermochemical energy storage has great potential to reduce this cost through the use of a reversible redox reaction pair that has a high enthalpy of reaction. The chemical nature...

Achilles Assistance Device as a Passive Ankle Foot Orthosis for Achilles Tendon Injuries

Creator:: Gonnerman, Evan J.
Abstract:: An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...

An Improved Chemical Kinetic Model Reduction in pyMARS for Liquid Propellants

Creator:: Moore, Cailin J.
Abstract:: The aerospace industry uses chemical kinetic models when designing propulsion systems to acquire specific details about the rate of chemical reactions, heat release, and combustion stability. These models, however, are too large and stiff to be useful as they can take weeks to run computations on. The pyMARS python package...

Technological Improvements in Ligation and Suturing Techniques: A Comparison in the Material Strength of Ligating Clips and Suturing Devices

Creator:: Robertson, Bria L.
Abstract:: Treatment of extrahepatic portosystemic shunts provides many options, including cellophane banding. These cellophane bands are secured with a ligation clip. Weck® offers two forms of these: the stainless steel Hemoclip, and the polymer Hem-o-lok. This in vitro study compares the mechanical strength of these two of types of clips by...

Numerical modeling of the hydrodynamics of gas fluidized beds

Creator:: Wang, Yusan
Abstract:: This research involves a numerical study of the hydrodynamics of gas fluidized beds. We use the continuum model, treating both gas and particles as interpenetrating continua. The motion of gas and particles is strongly coupled by the interactions between them. For simplicity, we only consider drag forces. We use MacCormack's...
