Thermal conductivity of rocks and its variation with uniaxial and triaxial stress

Thermal conductivities under high pressure in core samples from IODP NanTroSEIZE drilling site C0001

“…The pressure dependencies of thermal conductivity for dry samples of Rajasthan, Shirahama and Berea sandstones were similar (Figures 6c and 6d), and also similar to those of several previous studies for dry sandstones [ Woodside and Messmer , 1961; Demirci et al , 2004; Abdulagatov et al , 2006; Abdulagatova et al , 2009]. However, the thermal conductivities for each rock type were different, reflecting their different mineral compositions, porosities, environments of deposition, and geological ages.…”

Effect of temperature and pressure on the thermal conductivity of sandstone

“…ETC studies of the dry and fluid-saturated porous materials are useful in a number of other applications such as petroleum and natural gas geology [1][2][3][4], utilization of hydrothermal energy [5][6][7][8] and underground thermal energy storage [9,10], applications to geothermal problems and hydro-geological studies [11,12], civil engineering applications [13][14][15][16][17][18][19][20], composite materials [21][22][23], food and computer technologies, etc. [24].…”

Prediction of thermal conductivity of rock through physico-mechanical properties

“…The amount of heat to be transferred through any body depends upon a number of factors, such as the particle shape, porosity, temperature range, solid constituents, moisture content, uniaxial and/or triaxial pressure exerted on the rock, etc. [1][2][3][4][5]. It widely influences the energy transfer between adjacent rocks in underground mines and in insulation of the building by providing an energy efficient solution.…”
