Abstract:
Computer simulation and modeling of coupled heat and moisture transfer are becoming increasingly significant for accurate calculations of heat and moisture transfer. However, to solve their equations, the true component, {lambda}, of apparent thermal conductivity, {lambda}app, as a function of temperature, moisture content, and material structure is required. An approach to the development of a comprehensive database for {lambda} is discussed. Its key feature is demonstrated by the development of a theoretical model for {lambda} and {lambda} app of two common building insulation materials ¡ª expanded polystyrene insulation and highly porous calcium silicate ¡ª for a wide range of temperature and moisture conditions.
