Investigation of temperature effect on permeability of naturally fractured black coal for carbon dioxide movement: An experimental and numerical study

► Effect of temperature on permeability of naturally fractured coal. ► Triaxial test for experiments and COMET 3 software for numerical simulation. ► CO2 permeability increases with increasing temperature at high injecting pressures. ► Temperature does not affect much on CO2 permeability at low injecting pressures. ► Rate of permeability increment with temperature reduces after around 90 °C.
