Mathematical Model of Thermal Field for an Insulation Composite Wall In fact, the temperature field for an insulated composite wall belongs to a three-dimensional transient one .For simplification, we will employ following assumptions ① all the materials of the insulated composite wall are homogeneous and isotropic; ② thermo–mechanical parameters of all the materials are constants; ③ thermal resistance between two different materials is omitted; ④ only the temperature gradient takes place along the thick direction of the wall.
Thermo-mechanical parameters of all the materials are shown in Table.1 and Table.2. , , , , .
This is because the conductivity of the insulated material is much smaller than those of other materials.
