Prediction of the heat storage coefficient of a three-phase system

Abstract

A theoretical model for the heat storage coefficient (HSC) of an unsaturated and saturated medium containing three phases is presented using the geometry-dependent resistor model. To test the validity of the derived expression, the HSC of building materials saturated with different liquids have been measured. A plane heat source has been used to measure the HSC. A good agreement has been found between the experimental and the predicted values.
