Abstract:
Measurement of thermal properties like thermal conductivity, thermal resistivity, heat capacity and thermal diffusivity for Geo materials, it plays a crucial role in a wide range of various civil and electrical engineering projects, and many field applications like building's basement, power generation, underneath soil heating, wastes from nuclear as well as thermal plants, and buried cables. Thermal conductivity of soil depends upon various geotechnical parameters such as type of soil, moisture content, particle size distribution, density, and compaction characteristics. Earlier studies, the measurement of thermal conductivity of soil by incorporating the heat source methods. Thereby expensive and time taken to conduct in laboratory as well as field measurements. To overcome these limitations, advice is termed as an instrument to be fabricated for determination of thermal conductivity of geomaterials. Along with this, thermal probes also were fabricated and used in this work, and its efficiency in thermal conductivity determination of fabricated device has been evaluated by comparing the results obtained using laboratory thermal probes response. Typically, an instrument is designed as enormous in size. The details regarding this work were explained in this paper. Currently, a few various instruments are available in our country, which are too expensive and hence, an instrument needs to be fabricated as a portable device for measurement of thermal conductivity in lesser cost method. Finally, the fabricated instrument was calibrated with glycerin solution.
Key words: Geomaterials, Instrumentation, Thermal conductivity, Thermal probe.
