Resistor Model for Heat Storage Coefficient

Abstract

In thermodynamics, the heat storage coefficient (HSC) β of a material is defined as the square root of the product of the material's thermal conductivity and its volumetric heat capacity. A material's HSC is a measure of its ability to exchange thermal energy with its surroundings. A resistor model has been proposed by us in the following manner. In the case of soil materials, the solid particles are surrounded by fluid, or in the case of vacuum, by empty space. The HSC of such an unconsolidated system will depend on the conditions of porous media: porosity, temperature, HSC of different phases and the structure of the aggregate. The present model also yields values in good agreement with experimental results of other workers.
