RISHeliostat Attitude Control Strategy in the Solar Energy Research Facility of Valparaiso University
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a continuous tracking strategy for the heliostat in the James S. Markiewicz Concentrated Solar Energy Research Facility at Valparaiso University is developed. A model of the nonlinear dynamics of the heliostat ...
Measurement of the Natural Convection Heat Transfer in a Magnesium Oxide Electrolytic Cell Concept
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The rate of heat transfer by natural convection between the wall and electrolyte of an electrolytic cell that produces magnesium (Mg) from magnesium oxide (MgO) at temperatures near 1000 °C in a molten fluoride salt ...
Fungible, Multiyear Solar Thermochemical Energy Storage Demonstrated via the Cobalt Oxide Cycle1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a proof of concept demonstration of solar thermochemical energy storage on a multiple year time scale. The storage is fungible and can take the form of process heat or hydrogen. We designed and fabricated a 4-kW ...
Design of a Solar Reactor to Split CO2 Via Isothermal Redox Cycling of Ceria
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The design procedure for a 3 kWth prototype solar thermochemical reactor to implement isothermal redox cycling of ceria for CO2 splitting is presented. The reactor uses beds of mmsized porous ceria particles contained in ...
