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. In this second part, the method of homogenisation is used to capture the contrast of property between the gaseous phase and the solid phase.

Homogenisation problems are computed using a Control Volume formulation. The tracheid model developed in Part 1 has been used to define several elementary representative volumes. Consequently, bound water diffusivity and thermal conductivity can be predicted for each material direction as a function of local wood density. For practical applications, analytical models fitted from the computed values allow these property variations to be easily and accurately determined.

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.
