Computer-aided identification of transport properties of wood and wood-based panels

The concept of solving inverse heat and mass transfer problems with the use of optimization techniques and adequate mathematical models corresponding to direct problems of transport was applied to identify transport properties of solid wood and wood-based panels. The paper presents examples of the application of the inverse method in the following areas: thermal conductivity of solid wood in the three principal anatomic directions as a function of temperature, the diffusion coefficient dependency on the bound water content together with the boundary condition estimation, and gas permeability of mats during pressing of wood-based panels.
