Design, development, and validation of a low-cost measurement system for residential ground source heat pump systems
(2019-12)There is still relatively little data available to properly analyze the performance of Ground Source Heat Pump (GSHP) systems in residential applications. While commercial-grade instrumentation is available, it is often ... -
Development of computer programs for fast computation of g-functions and automated ground heat exchanger design
(2021-12)Ground-source heat pump systems utilizing vertical borehole ground heat exchangers are energy efficient. The most accurate method for sizing the boreholes is based on simulations which make use of superposition of a unit-step ... -
Laboratory scale evaluation of compliant drillstring with PDC bits in geothermal applications
(2022-05)Polycrystalline diamond compact (PDC) bits have shown tremendous performance compared to roller cone bits and have gained attraction in deep geothermal drilling applications. While PDC bits can reach a higher rate of ... -
PDC drill bit modeling in hard rock
(2020-05)The objective of thesis is to develop a detailed PDC drill bit ROP model that can be implemented in a real time drilling optimization system for hard rock application. Within the drilling industry, often times operational ...
