Abstract

Presented CFD-model considers coupled vapor and moisture transfer processes in porous building materials. In contrast to the existing models, it takes into account the ratio between vapor and moisture components in accordance with the building materials’ sorption curve. The specific analysis of the model development in ANSYS-FLUENT is presented and the results are compared with experimental data of the gas concrete humidification.
