Capillary Moisture Transfer Modeling of Softwoods Based on Pore Size DistributionMeasurements

摘要

In the present work capillary moisture transfer modeling of softwoods is based onthe theory of coupled capillary tubes and on measured pore size distributions of softwoods. The heartwood and sapwood pore size distributions measured for softwoods in a previous study are used as basis of the modeling. The modeling is carried out by applying authors previously developed CAPILLARY TUBE MODEL method to radial absorption of pine (pinus silvestris) and spruce (picea abies). The model aims at expressing the moisture distribution during water absorption in radial direction and computing the moisture diffusivities as a function of moisture content.
