Thermo-TDR Probe for Measurement of Soil Moisture, Density, and Thermal Properties
Geothermal energy, particularly shallow geothermal energy, has become increasingly popular in the geotechnical engineering community. Design of optimized and efficient geothermal systems requires better understanding of soil thermal behavior, which relies on accurate characterization of soil thermal conductivity, along with moisture and density. In this study a thermo-TDR probe was designed and evaluated against a standard heat probe for thermal property measurement. In addition, the probe also enables the simultaneous measurement of moisture and density, along with thermal conductivity. This unique feature makes it possible to obtain high-quality data for geothermal-related studies. Ottawa sand and kaolin clay soils at different moisture conditions were tested using the developed thermo-TDR probe. The obtained data show the thermo-TDR probe can measure moisture content and density and thermal properties with reasonable accuracy.
