Abstract

A CFD-model to simulate the conjugate heat and moisture transfer between the building envelope surface and internal air-steam-medium layer with radiation and convective heat transfer. was developed with ANSYS-FLUENT software. The conjugate heat and moisture transfer is realized using of specially created function, that expanded calculated capabilities of ANSYS-FLUENT software. Obtained temperature and absolute humidity distributions with sufficient accuracy correspond to the experimental data.
