Wood is a natural and highly anisotropic material. Therefore, mechanical characteristics of the material depend on the direction of wood. In this paper, we propose to describe the transfer of the water inside the wood in two dimensions by immersing the sample in liquid water. The potential which drives the transport of water through the wood is controlled by the diffusion transient process. A model based on a numerical finite difference method has been found to follow the absorption process of water above the fibers saturation point of two-dimensions.

“…A mathematical model can be used to understand and predict drying time and wood quality (Haque 2002). In addition, an accurate mathematical model will be effectively used to evaluate the effect of drying regimes on the drying behavior of wood (Yuniarti et al 2018).…”

This study investigated the mass transfer properties (permeability and mass diffusivity) in the longitudinal, radial and tangential directions of plantation-grown Acacia mangium in VinhPhuc province,northeast, Vietnam. These properties will be used to complement a conventional drying model in the future. Measurements of gas and liquid permeability were performed using a Porometer (POROLUX TM 1000). Mass diffusivity was determined in a constant humidity and temperature chamber using PVC-CHA vaporimeters. Results showed the gas permeability was significant higher than liquid with the descending order of longitudinal, radial, and tangential directions. The permeability anisotropy ratios from the longitudinal to transverse directions of Acacia mangium were much lower than other published species. However, the obvious anisotropy ratios from radial to tangential for both permeability and diffusivity, is one of concerns as they can exacerbate defects during drying. Besides, the high permeability and diffusivity of Acaciamangium compared to some other species reported compounds its relatively fast drying rate.
