This study investigates the effect of water repellency on the thermal and electrical conductance of soils. A transient line source heating method and two-terminal electrode system was used to investigate the thermal and electrical conductivity of unsaturated hydrophilic and hydrophobic soils with known degrees of water saturation. A controlled drying process was used to carefully control the saturation....
Compacted bentonite and a bentonite–sand mixture have been considered as a potential buffer material for nuclear waste stored underground. The effects of dry density, water content and sand fraction on the thermal conductivity of the mixtures were investigated via data collected with the transient line source technique. With those parameters known, a single expression for the thermal conductivity of the mixture ...
The transient line source technique was used to take thermal conductivity measurements over the entire liquid range of toluene at 1atm. Unlike any other liquid (with the exception of water) the thermal conductivity was not completely a linear function of temperature. Instead, there was an anomaly pre-freezing where the thermal conductivity dropped from what was expected. This paper attributes this behavior to ...
Testing of thermal properties of foods is essential for operation and control of food processing plants. In this paper, the thermal conductivity of rice and the drying of cooked rice is measured. These measurements are determined using a transient line source over a temperature range of 50-70°C, a moisture content range of 10-70%, packing density range of 500-850 Kg/M3Author(s):M. N. Ramesh
Wood can be defined as a composite, porous material as it is effectively made of two different substances. This property is reflective of how differently the wood grows with respect to the four seasons and how the materials in the wood can change based on ambient heat. The constant change in seasons therefore forms wood grains, which show the differing thermal properties of wood material. This paper finds the apparent ...
