Turbulent Combustion Analysis of Large Hydrocarbon Fuels in a Reduced Pressure Environment

Creator:: Schorn, Nathan E.
Abstract:: The aviation industry is pushing for better fuels and gas turbine engines for several reasons: cost, emissions, and to a lesser extent high-altitude relights. One aspect that research has been focused on to help reduce costs, emissions and better understand high-altitude relights is studying the combustion behavior of the fuel...

Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...

Analysis of spillway hydrodynamics for total dissolved gas prediction downstream of hydropower projects with free, plunging spillway jets

Creator:: Germann, Nathan A.
Abstract:: During spring and early summer hydropower projects are often forced to spill water through their spillways due to increased river flows of the runoff season. Flows which are directed through spillways--instead of through turbines--contain a substantial amount of energy. Stemming from the high energy content, spillway flows entrain air at...

The Design of a Multidisciplinary Capstone Course

Creator:: Rust, Nathan R.
Abstract:: The end goal of any educational program is to prepare a student for the challenges they will see after completion of their studies. In the realm of engineering, the pinnacle of this occurs during a student’s final Capstone course series, where students are asked to apply their various skills learned...

Modeling and control of a biologically inspired compliant structure

Creator:: Ray, Cody W.
Abstract:: We hypothesize that the extraordinary maneuverability and efficiency of bats in flight are in part due to the compliant nature of their wing structures. We utilize the parameters of bat bones measured by biologists to create a biologically inspired model of a flapping system consisting of a rotating hub actuator...

Topological Design Considering Uncertainty and Hyperelasticity

Creator:: Pham, Trung
Abstract:: Topology optimization (TO) is a mathematical method to find the optimal size, shape and connectivity of a domain under specified conditions, and has had many applications in engineering design. However, challenges remain in realizing TO as an effective design tool for many design situations. Uncertainty is ubiquitous in nature and...

Bi-level flexible-robust optimization for energy allocation problems

Creator:: Biswas, Arpan
Abstract:: A common problem in energy allocation problems is managing the trade-off between selling surplus energy to maximize short term revenue, versus holding surplus energy to hedge against future shortfalls. For energy allocation problems, this surplus represents resource flexibility and is quantified as the surplus energy after meeting the demand. The...

From Functional Modeling to Optimization : Risk and Safety in the Design Process for Large-Scale Systems

Creator:: McIntire, Matthew G.
Abstract:: In order to more effectively design large, complex systems, risk must be accounted for throughout the design process. A systematic way to account for risk is by using system model simulation. During the conceptual design phase, functional models can be drawn to help the engineer design their system's functional architecture....

Hybrid Statistical and Engineering Optimization Architectures in Early Multidisciplinary Designs of Resilience and Expensive Black-box Complex Systems

Creator:: Biswas, Arpan
Abstract:: Practical engineering design problems are generally multi-disciplinary with limited budget and high risk in terms of life loss, economic resources, etc. In the early phase of such problems, selection of true efficient designs is desired while minimizing overall design cost by avoiding expensive search processes. However, the task is difficult...

The geometric characterization and thermal performance of a microchannel heat exchanger for diesel engine waste heat recovery

Creator:: Yih, James S.
Abstract:: Rising energy demands and the continual push to find more energy efficient technologies have been the impetus for the investigation of waste heat recovery techniques. Diesel engine exhaust heat utilization has the potential to significantly reduce the consumption of fossil fuels and reduce the release of greenhouse gases, because diesel...
