In this work, the effect of mechanical damage on the thermal conductivity of granite was experimentally investigated. Granite samples were artificially damaged through cyclic loading and unloading tests, with the strain evolution and acoustic emission activity monitored simultaneously. P-Wave velocity of ...
Granite, a siliceous aggregate, which consists of quartz and feldspar predominantly, possesses thermal conductivity of about 3.5 W/mK [147]. Carbonaceous and calcareous aggregates are majorly composed of limestone and dolomite whose thermal conductivities range from 2.9 to 3.3 W/mK and 5.3 to 6 W...
Based on the theory of thermal conductivity, in this paper we derived a formula to estimate the prolongation period (ΔtL) of cooling-crystallization process of a granitic melt caused by latent heat of crystallization as follows: where TM is initial temperature of the granite melt, TC ...

Prediction of thermal conductivity of granite rocks from porosity and density data at normal temperature and pressure: In situ thermal conductivity measurements. J. Phys. D Appl. Phys. 2004, 37, 3396. [Google Scholar] [CrossRef] Gegenhuber, N.; Schoen, J. New approaches for the relationship...
Thermal conductivity coefficients for insulation materials, aluminum, asphalt, brass, copper, steel, gases and more.
Thermal diffusivity, heat capacity, and thermal conductivity of Central Aare granite are reported in the temperature range from 25°C to 500°C. Each rock sample underwent three consecutive heating and cooling cycles. Significant irreversible changes in the properties due to thermal crack formation co...
The formation of thermal fractures in a geothermal reservoir will be governed by the thermophysical properties of the reservoir rock, including heat capacity, thermal conductivity, coefficient of thermal expansion, etc. Thermal conductivity may be estimated using data obtained from geophysical well logs....
To assess the gains and limitations of TSVs in integrated systems, systematic approaches are provided for inserting and distributing the vertical interconnects to improve the overall thermal conductivity of a 3-D stack. By including the thermal objective in 3-D physical design algorithms and technique...
