  • An experimental study of the fluid mechanics of filling a small part of modular mold

    Creator:
    Miller, Mark Wade, 1967-
    Abstract:
    Investment casting has been an important form of metal casting for many years, but little is understood about the fluid flows that occur during mold filling. A key to quality castings is the understanding and control of the fluid flows that are present when the mold is filled with molten...

  • Aircraft wing optimization using B-spline models and panel methods

    Creator:
    Jackson, Danielle Monique
    Abstract:
    This research investigates shape optimization process, using b-spline models and panel methods, to achieve a high lift to drag ratio for an aerodynamic structure. This research is a proof of concept for further research in aerodynamic shape optimization. The coupled process, involving the design and optimization of a random shape,...

  • Systematic design of biologically-inspired engineering solutions

    Creator:
    Nagel, Jacquelyn Kay
    Abstract:
    Biological organisms, phenomena and strategies, herein referred to as biological systems, provide a rich set of analogies that can be used to inspire engineering innovation. Biologically-inspired, or biomimetic, designs are publicly viewed as creative and novel solutions to human problems. Moreover, some biomimetic designs have become so commonplace that it...

  • Advanced numerical modeling of the Lorentz mixing process

    Creator:
    Hager, Michael B.
    Abstract:
    There are numerous techniques for improving the mixing of fuel and oxidant species. However, many of these methods cannot be applied to combustion systems due to material limitations. A means of mixing the reacting species without physically invading the flow stream is therefore desired. In this work, induced electromagnetic forces...

  • A study of a diffusionally controlled reactive synthesis process using a multi-tube diffusion flame burner

    Creator:
    Snell, Douglas C.
    Abstract:
    A continuous process for the production of ceramic materials has been studied. This method reacted metal and oxidizer in a diffusionally controlled process, demonstrated by reacting a magnesium particle stream and hot water vapor. Many small rich hydrogen/air diffusion flames provide an atmosphere of hot water vapor, hydrogen, and nitrogen...

  • Temperature measurement, electrical characteristics, and lorentz mixing of alkali seeded flames

    Creator:
    Pattee, Heidi Ann
    Abstract:
    When trace quantities of an alkali element are added to a flame, its optical and electrical properties change significantly. Addition of alkali seed to both premixed and diffusion flames has been used in the development of two new techniques, one for flame temperature measurement and the other for enhanced mixing....

  • Micro adiabatic combustion engine : concept development, simulation and combustion experiments

    Creator:
    Chewning, Scott R.
    Abstract:
    The current proliferation of portable electronic devices for personal communication, business and entertainment has created a demand for high energy density power supplies. A hydrocarbon fuel with a conversion efficiency of over 15% can provide greater energy density than current battery technology for these applications. Current micro-scale heat engines do...

  • Development of a small scale scroll expander

    Creator:
    Harada, Kevin J.
    Abstract:
    The organic Rankine cycle (ORC) is a versatile approach in the utilization of waste heat in the production of electricity, clean drinking water, and cooling. The efficiency of these cycles must be maximized to make them economical. Parameters for the optimization of ORCs such as evaporator and condenser temperature have...

  • A design framework for identifying automation opportunities

    Creator:
    Nagel, Robert Lewis, 1982-
    Abstract:
    Since the Industrial Revolution, automated systems have increasingly become a part of everyday life. Automated systems range in scale and scope from simple assists to complete robotic replacements. Inexpensive integrated circuits, sensors and microprocessors have allowed automated systems to become smaller, cheaper and more prevalent. Identifying appropriate opportunities for automation,...

  • Natural convection from a horizontal cylinder parallel to a heated vertical wall

    Creator:
    McCoy, Timothy J.
    Abstract:
    Heat transfer measurements have been made from a long (L/D = 15) horizontal cylinder in water parallel to a heated vertical wall. The cylinder and wall boundary conditions were isothermal, and they were maintained at equal temperatures. The investigation covered Rayleigh numbers based on cylinder diameter from 400,000 to 10,000,000....
