| Abstract | Saturation water content and liquid diffusivity are two important parameters that influence hygrothermal simulation results, particularly when investigating the performance of wood-frame walls subjected to rainwater penetration. In this paper, the impact of saturation water content (free water saturation and effective saturation) of OSB in a wood-frame wall subjected to water penetration was assessed through hygrothermal simulations using two programs—WUFI and DELPHIN. The results derived from DELPHIN showed that the model using free water saturation and that using effective saturation had significant differences in the simulated moisture content of OSB during the water penetration period, whereas results obtained from WUFI did not indicate such differences. Thereafter, the accuracy of three liquid diffusivity equations and their influence on simulation results was assessed based on the free water saturation model by WUFI. The derived liquid diffusivity did not accurately reflect the measured liquid diffusivity of OSB, and the simulation results using derived liquid diffusivity were considerably different from those using measured liquid diffusivity. |
