Nonlinear Photothermal Radiometry And Its Applications To Pyrometry And Thermal Property Measurements, Austin Drew Fleming
Nonlinear Photothermal Radiometry And Its Applications To Pyrometry And Thermal Property Measurements, Austin Drew Fleming
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Accurate temperature and thermal property measurements are critical for the modeling and prediction of heat transfer. In many industries thermal management is a limiting factor of performance, and rely on advanced modeling techniques to develop and design methods to better manage thermal energy. This study expands the thermal property and pyrometry measurement capabilities by developing three new techniques based on thermal emission’s nonlinear dependence on temperature.
Statistical Models Of I-15 Bridge C-846: Changes In Natural Frequencies Due To Temperature, Gilbert Nichols
Statistical Models Of I-15 Bridge C-846: Changes In Natural Frequencies Due To Temperature, Gilbert Nichols
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Structural Health monitoring is to determine the condition of a bridge based on instrument measurements. The C-846 Bridge in Salt Lake City has such instrumentation. The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.
In light of recent research, damage may be detected from measuring the change in …
Prestress Losses And Temperature Effects On A Deck Bulb Tee Girder Bridge, Phillip Powelson
Prestress Losses And Temperature Effects On A Deck Bulb Tee Girder Bridge, Phillip Powelson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The Utah Transportation Center (UTC), in partnership with the Mountain Plains Consortium (MPC), sponsored a study to investigate the differences in prestress losses and temperature gradients in a concrete deck bulb tee girder bridge. The Millville Bridge was built as an access point to the Ridgeline High School in Millville, Utah. The bridge was built in 2016 and presently supports two lanes of traffic.
Changes in prestress were measured with a total of 16 vibrating wire strain gauges located at four cross-sections. Temperature gradients were measured with a total of 50 thermocouples located at five cross-section locations, four of which …
