  • Assessing steel bevel gear design alternatives for sustainability performance through unit manufacturing process modeling

    Creator:
    Eastwood, Michael D.
    Abstract:
    As the growth in demand for sustainable manufacturing continues, companies must begin to make conscious design decisions with regard to the sustainability of their products. This means balancing economics of production with environmental and social performance. Thus, design and manufacturing engineers must consider economic, environmental, and social aspects simultaneously when...

  • Assisting decision making in component design for sustainable manufacturing

    Creator:
    Eastlick, Dane D.
    Abstract:
    Current life cycle assessment tools are often deficient in assisting design for sustainable manufacturing efforts. Integrating an improved assessment method into a decision support framework will provide a means for designers and engineers to better understand the impacts of their decisions. A unit process modeling-based sustainability assessment method is presented...

  • Characterization of Two Novel Machining Processes for Difficult to Machine Materials

    Creator:
    Doran, Michael P.
    Abstract:
    New materials with superior mechanical properties, such as increased strength and hardness, have been developed to allow for new and improved products. However, the mechanical properties that make these materials useful also makes them difficult to process using conventional methods. New machining processes need to be developed to generate products...

  • An Information Modeling Framework for Support of Sustainable Manufacturing System Design Decision Making

    Creator:
    Shankar Raman, Arvind
    Abstract:
    Manufacturing technology has continuously evolved and advanced over the past century; this has led to an increase in the production of consumer and industrial goods driven by simultaneous growth in population and wealth. Despite the resulting economic and labor growth, environmental impacts of manufacturing have increased dramatically due to the...

  • Identification of Barriers to Industrial Energy Efficiency Improvement in the Pacific Northwest

    Creator:
    Martz, Allison M.
    Abstract:
    The US industrial sector accounts for about one-third of the nation’s energy consumption and is predicted to grow twice as quickly as other sectors through 2050. International organizations such as the International Energy Agency project energy efficiency improvements will account for over 40% of greenhouse gas emissions reductions through 2040....

  • A Computational Fluid Dynamics Investigation of Hemolysis Potential in a Microfluidic Hemoperfusion Device Designed for Use in Sepsis Treatment

    Creator:
    Myers, Karl N.
    Abstract:
    The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...

  • Automated Rapid Manufacturing Feedback for Design Considering Advanced Joining Processes

    Creator:
    Chan, Rothanak
    Abstract:
    As manufacturing advancements continue to develop, designers must be able to consider these technologies during the design process. Unfortunately, many of these new technologies, such as additive and advanced joining, have many nuances that require expert knowledge to effectively apply. Additionally, new design techniques, such as topology optimization, allow users...

  • Modeling hop kilning with respect to energy consumption and drying kinetics

    Creator:
    Thomas, Matthew W.
    Abstract:
    Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...
