Design and performance of a small scale waste heat recovery unit

Creator:: Ward, Christopher
Abstract:: A microchannel heat exchanger was designed for diesel waste heat recovery and its performance was evaluated. The 21x15x8 cm unit was constructed from diffusion brazed stainless steel lamina and weighed 11 kg. Operating from a 13.4 kW generator with an exhaust temperature of 500 °C the unit delivered 11.1 kW...

Enterprise system implementation projects : a study of the impact of contextual factors on critical success factors

Creator:: Van Scoter, Diane J.
Abstract:: Critical success factors (CSFs) are those things that must be done correctly for a project to be successful; however, CSFs are not sufficient by themselves to guarantee success. CSFs, as identified in the literature, vary from study to study. In addition, previous studies have not typically included contextual details for...

Evaluating the effectiveness and efficiency of continuous improvement training

Creator:: Wiseman, Lindsay M.
Abstract:: Training is a key business process used to increase the skills and knowledge of employees in an effort to improve overall performance. Evaluation of the effectiveness and efficiency of training processes is necessary to ensure time, money, and resources are used to provide the most benefit possible. This investigation is...

Experimental study of impulse turbines and permanent magnet alternators for pico-hydropower generation

Creator:: Cobb, Bryan R.
Abstract:: Increasing access to modern forms of energy in developing countries is a crucial component to eliminating extreme poverty around the world. Pico-hydro schemes (less than 5-kW range) can provide environmentally sustainable electricity and mechanical power to rural communities, generally more cost-effectively than diesel/gasoline generators, wind turbines, or solar photovoltaic systems....

Exploring experimental test stand design and operation within a system reliability research methodology

Creator:: Koopmans, Michael, 1986-
Abstract:: In cases where complex systems routinely experience extreme operating conditions, preventative maintenance is often employed to guard against system failure. Yet, with accessible real-time data and the standard practice becoming prohibitively expensive, the test stand can serve as a vital contributor to the development of system health and reliability estimations....

Force and impulse control for spring-mass running

Creator:: Koepl, Devin N.
Abstract:: We present a novel control strategy for running which is robust to disturbances, and makes excellent use of passive dynamics for energy economy. The motivation for our control strategy is based on observations of animals, which are able to economically walk and run over varying terrain and ground dynamics. It...

Fracture toughness of void-site-filled skutterudites

Creator:: Eilertsen, James S.
Abstract:: Thermoelectric materials are playing an increasingly significant role in the global effort to develop sustainable energy technologies. Consequently, the demand for materials with greater thermoelectric efficiency has stimulated the development of state-of-the-art interstitially doped skutterudite-based materials. However, since intermetallics are often embrittled by interstitial substitution, optimal skutterudite-based device design, manufacture,...

Global distributed design of a Formula SAE race car

Creator:: Carpenter, Trenton J.
Abstract:: Future engineers need to be competitive in today's expanding global industries. They must have capabilities beyond standard engineering practice. In an attempt to develop students capable of working in a globally distributed design and manufacturing environment, Oregon State University (OSU) and Duale Hochschule Baden-Württemberg Ravensburg (DHBW) have developed a senior...

Hydroelastic modeling of a wave energy converter using the arbitrary Lagrangian-Eulerian finite element method in LS-DYNA

Creator:: Meicke, Stephen A.
Abstract:: This thesis investigates the applicability of the finite element method to model wave energy converter (WEC) hydroelasticity using LS-DYNA. The proposed methodology uses the Arbitrary Lagrangian-Eulerian formulation to model Fluid-Structure Interaction (FSI) between the WEC and the fluid elements. This formulation allows for time-domain modeling of higher order effects such...
