  • Understanding Drivers of Glacier Length Variability Over the Last Millennium

    Creator:
    Huston, Alan C.
    Abstract:
    Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

  • Solar Thermal Energy System for Renewable Desalination

    Creator:
    McLaughlin, Ryan P.
    Abstract:
    Natural freshwater availability is decreasing as the global population increases. Advances in desalination technologies aim to produce fresh water in an economical way. More sustainable energy sources are desired for these desalination plants to limit the carbon footprint of water production since global carbon dioxide production is exacerbating freshwater scarcity....

  • Reactive Phase Change Materials for Enhanced Thermal Energy Storage

    Creator:
    Drake, Griffin S.
    Abstract:
    Effective storage and release of low-to-moderate temperature thermal energy (e.g. solar thermal or geothermal) could be transformational for applications such as space heating/cooling, domestic hot water, or off-grid cooking. Good candidates for thermal energy storage in this temperature range include latent heat storage (LHS) systems and thermochemical energy storage (TCES)...

  • Particle Movement in a multi-chamber fluidized bed

    Creator:
    Tan, Chuan Hao
    Abstract:
    The goal of this project is to better characterize particle movement in a multi-channel fluidized bed. Fluidized beds are commonly used for heat transfer with the rapid fluidization and homogeneous heat distribution. By characterizing this particle flow, it would allow for an improved understanding of the heat transfer mechanisms within...

  • Ultraviolet photolysis of acetaminophen in a 3D printed continuous flow reactor

    Creator:
    Goetze, John M.
    Abstract:
    Finding renewable sources of agricultural fertilizer will be necessary to ensure a stable food supply for future generations. Phosphorus is of particular concern, since mining phosphate rock is the main source and reserves are forecasted to deplete in the next 50 – 200 years. Human urine contains substantial amounts of...

  • Incorporation of polymorphic spacers to inhibit sintering of SrO/SrCO3 for thermochemical energy storage

    Creator:
    Tran, Justin T
    Abstract:
    Global energy needs are continuously increasing while fossil fuels remain an uncertain resource. With a growing population and demand for energy, alternative energy sources are being pursued to power the future. Fossil fuels are an unsustainable resource that brings along problems of climate change and atmospheric pollution. Concentrated solar power...

  • Thermodynamic analysis of a magnesium carbonate thermochemistry and compressed air energy storage system

    Creator:
    Rebarchik, Eric R.
    Abstract:
    In this work, a hybrid thermochemistry compressed air energy storage (CAES) system is investigated. Following a review on chemical reactions investigated for use in thermochemical energy storage (TCES) systems, from these chemistries, the conversion of magnesium carbonate, MgCO3, to magnesium oxide, MgO, and carbon dioxide, CO2, was further analyzed for...

  • Power Generation via a Thermoelectric Generator Driven by a Reversible Exothermic Reaction

    Creator:
    Bhatt, Renuka J.
    Abstract:
    Solar thermal energy can be stored and later converted to electrical energy using a combination of thermochemical energy storage (TCES) and a thermoelectric generator (TEG). This TEG and TCES combination illustrates a potential route for clean electricity storage from renewable energy. TCES allows for thermal energy from the sun to...

  • Advanced Solvent Purification Process Design using Aspen HYSYS and Feasibility Studies

    Creator:
    Meeuwsen, Rachel M.
    Abstract:
    High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...

  • Two Step Oleofuran Production from Furfural and Fatty Alcohols

    Creator:
    Gadinas, Nicholas L.
    Abstract:
    A present abundance of biomass and a decreasing supply of petroleum signal the need for efficient pathways from renewable feedstocks to high value chemicals. One such class of chemicals is oleofurans, molecules comprised of a furan ring and carbon chain which can be used to make powerful hard water surfactants....
