COUPLED HEAT AND MOISTURE TRANSFER IN UNSATURATED SOIL FOR THE MODELING OF SHALLOW HORIZONTAL GROUND LOOPS
Wu, Ray (2014-01-03)INTRODUCTION In recent decades, ground-source heat pump (GSHP) systems have received considerable attention as an energy efficient technology for residential and commercial heating and cooling. Approximately 50,000 GSHP ... -
District-Scale Ground Heat Exchange Performance with Fiber Optic Distributed Temperature Sensing
McDaniel, Adam Louis (2018-01-03)Chapter 1: Introduction Ground-source heat pumps (GSHP) systems have great potential as an energy-efficient alternative to conventional space heating and cooling systems. The basic principal behind GSHP technology is ... -
DURABILITY PERFORMANCE OF CEMENTITIOUSLY STABILIZED LAYERS
Su, Zhipeng (2012-05-20)The ability to retain stability and integrity over years of exposure to the destructive forces of weathering is one of the most important aspects of cementitiously stabilized layers (CSL) in pavement design. However, the ... -
Impact of Increasing Freight Loads on Rail Infrastructure from Fracking Sand Transportation
Hesse, Damien Edward (2014-01-03)The increased use of the hydraulic fracturing technique, used extensively in the United States, for oil and natural gas extraction, has significantly expanded the frac sand market and impacted freight rail corridors. This ... -
Leaching from Roadways Stabilized with Additive Coal Combustion Products (CCPs): Data Assessment and Synthesis
Brown, Brigitte Leora (2015-05-17)Approximately 37% of the electrical power used in the United States is generated by coal-fired power plants. Air pollution control systems installed on coal-fired power plants collect solid byproducts of coal combustion, ... -
Mechanical Behavior of Polyurethane Stabilized Fouled Ballast (PSFB)
Dolcek, Tolga (2014-05-18)The United State Federal Railway Administration (FRA, 2010) estimates that the demand for rail freight transportation (tonnage) will increase 88% by 2035. North American railroads spend about $3.4 billion every year on ... -
Residential and District-Scale Ground-Coupled Heat Pump Performance with Fiber Optic Distributed Temperature Sensing
Walker, Matthew Dean (2015-05-17)Ground-coupled heat pumps (GCHP) have garnered considerable attention in recent years as an energy-saving alternative to conventional space heating and cooling systems, but there exists some debate about their effectiveness ... -
Thermophysical Properties of Wisconsin Rocks for Application in Geothermal Energy
Meyer, Lauren L. (2013-05-19)Limited information exists about the geothermal gradient and heat capacity of the geologic formations in Wisconsin. The viability of deep (? 300 m) geothermal exchange systems in Wisconsin depends on the thermal properties ...
