  • Optimization of staged rankine energy conversion cycles for high efficiency

    Creator:
    Simmons, Larry Dean
    Abstract:
    Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...

  • Analysis of energy conversion systems, including material and global warming aspects

    Creator:
    Zhang, Mingyuan
    Abstract:
    With the rapid increase of the world energy demand and consumption, the method and techniques to analyze, improve and optimize energy conversion systems have to deal not only with direct fuel exergy (energy) consumption, but also with other resources, which have associated exergy consumptions, and with environmental impacts, such as...

  • Efficient power conversion interface circuits for energy harvesting applications

    Creator:
    Le, Triet T.
    Abstract:
    Harvesting energy from the environment for powering micro-power devices have been increasing in popularity. These types of devices can be used in embedded applications or in sensor networks where battery replacement is impractical. In this dissertation, different methods of energy harvesting from the environment are explored as alternative sources of...

  • Testing of wave energy converters using the Ocean Sentinel Instrumentation Buoy

    Creator:
    Lettenmaier, Terrance
    Abstract:
    Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...
