Abstract

In this work, the extensive knowledge of wood gained at the Ecole Nationale du Genie Rural des Eaux et Forets by using a combination of microscopic observation and experimental work is being used to postulate material property correlations for a macroscopic heterogeneous "Cerne" growth ring model of softwood. Mathematical tools such as image analysis and homogenisation are used to develop models that capture the effect of the density variation within the wood sample of important macroscopic physical parameters. This first part is devoted to mass transfer in wood due to Darcy's law. Capillary pressure correlations as a function of local density are deduced from image analysis. Thereafter, a tracheid model is proposed for softwood. Its shape evolves from earlywood to latewood according to anatomical observations. Liquid and gaseous permeability values are calculated from this model according to Poiseuille's flow within cells and assuming a linear flow-pressure loss relationship through the pits.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
