Numerical Modeling of Heat and Moisture Diffusion in Porous Materials
Tóm tắt
The article describes a one-dimensional model of heat and moisture transfer in a building wall constructed from several layers of different porous materials. The model consists of a system of diffusion equations for heat, water vapor, and liquid water allowing for condensation of vapor and evaporation of water. An algorithm and a computer program are developed for numerical solution of the model equations by the finite-difference method. Two examples are given calculating the heat and moisture regime of constructions over a 50-year period with allowance for seasonal changes of temperature and air humidity.
