Abstract

With a view to reducing heat and mass transfer within the envelope of the building constructed with BTC, numerical modelling of coupled heat and mass transfer was carried out. The model is based on the work of Luikov. The mathematical model governing heat and mass transfer was established using temperature and moisture content as the main variables. The problem was tackled using a numerical approach based on the finite element method. Implementing the mathematical model in COMSOL Multiphysics enabled us to obtain very satisfactory results. These results enabled us to represent the spatiotemporal distribution of temperature fields and moisture content within the wall studied. Half a day's numerical simulation shows that the heat and humidity do not penetrate the entire wall.
