Hygrothermal Behaviours of Wood Column Exposed to Outdoor Weather during One Month

This article presents the numerical simulation results. The governing equation was developed using assumption on the moisture driving potentials and the phenomenological coefficients. The simulation results by control volume finite element method were compared to experimentally estimated results. The effect of moisture transfer rate on the heat diffusion was not significant because the heat diffusion was much faster than the moisture diffusion. The average temperature and its distribution under external dynamic conditions calculated using apparent heat diffusion coefficient were similar from the engineering point of view.
