Studying the Temperature Dependence of Thermal Conductivity in a Rock of Combined Composition

A model for the structure of a rock as a heterogeneous system of two components, amorphous and crystalline, is considered. A formula is proposed for calculating the thermal conductivity of rocks with different temperature dependences of the thermal conductivity of their components. When the temperat...

Description
Summary:A model for the structure of a rock as a heterogeneous system of two components, amorphous and crystalline, is considered. A formula is proposed for calculating the thermal conductivity of rocks with different temperature dependences of the thermal conductivity of their components. When the temperature dependence of the thermal conductivity of the components and their volume fractions is known, the thermal conductivity of the actual rock can be predicted for different combinations of amorphous and crystalline phases.
