Granite coefficient of thermal expansion
WebNov 4, 2024 · Regardless of how the thermal expansion coefficient is calculated, the first step is to fully relax the crystal structure (lattice parameters and internal atomic coordinates) of interest. All the relaxations described below are 0 K calculations. The calculations were performed with DFT, as implemented in Quantum Espresso. 48 48. P. WebThis study experimentally analysed the influence of temperature levels (200, 300, 400, 500, 600, and 800 °C) on the permeability of granite samples. At each temperature level, the applied confining pressure was in the range of 10–30 MPa, and the inlet hydraulic pressure varied below the corresponding confining pressure. The results are as follows: …
