Application of Effective Media Theory for Determination of Thermal Properties of Hollow Bricks as a Function of Moisture Content

Popis výsledku v původním jazyce

The effective thermal conductivity and effective specific heat capacity of hollow brick blocks are investigated as a function of moisture content.While the effective specific heat capacity as a heat storage parameter is calculated using the linear theoryof mixtures, the effective thermal conductivity as a heat transport parameter is analyzed using the effective media theory. At first, the effective thermal conductivity of the dry hollow brick block is calculated using a combination of properties of thebrick body and air cavities, and verified using experimental data. Then, the effective thermal conductivity of the brick body is analyzed as a function of moisture content both theoretically and experimentally, and appropriate homogenization formulas are identified. Finally, the effective thermal conductivity of the whole hollow bricks is expressed as a function of moisture content from the dry state to water saturation.
