EFFECTIVE HEAT AND MOISTURE TRANSPORT PROPERTIES OF SPRUCE


Abstract eng:
The present paper is devoted to the determination of effective properties of wood needed in the macroscopic description of heat and moisture transport in the framework of multi-scale computational scheme. Although computationally feasible, we do not attempt to account for all microstructural details and instead adopt a simplified analytical micromechanical model based on the Mori-Tanaka homogenization scheme to derive effective thermal conductivities of wood and effective diffusivities for the bound water present in the cell wall of wood and water vapor transported through lumens. As one particular example we consider a spruce wood as representative of softwood and most common in the production of glued laminated timber beams.
