Modeling of Coupled Moisture and Heat Transfer During Wood Drying
Development of an accurate mathematical model of sufficient generality to evaluate drying processes in materials having diverse moisture transport properties is proposed. The process of wood drying is interpreted as simultaneous heat and moisture transfer with local thermodynamic equilibrium at each point within the timber. The model is a mathematical one treating wood as a continuous and homog...
متن کاملDetermination of the controlling resistance to moisture transfer during drying
In this study the correlation between lag factor G and Page ́s mathematical model parameter n was developed. Using the newly developed correlation the presence of internal or external resistance to moisture transfer during thermal drying can be verified. As modeling tools Artificial neural networks (ANN) and Adaptive neuro-fuzzy inference system (ANFIS) were used. The best model for determinatio...
متن کاملEffects of Veneer Drying at High Temperature and Chemical Treatments on Equilibrium Moisture Content of Plywood
Moisture content (MC) is one of the most important factors that can affect many physical and mechanical properties of wood and veneers. MC strongly affects the final strength and durability of joints, development of surface checks in the wood and dimensional stability of the bonded assembly. In this study, plywood panels made from Alnus glutinosa (Alder), Fagus orientalis (Beech) and Picea orie...
متن کاملMoisture-induced Distortion of Laminated Veneer Products
Laminated veneer products consist of veneers bonded together with adhesive into a predetermined shape. Since wood is a hygroscopic material and also anisotropic by nature, laminated veneer products are especially shape-sensitive to changes in moisture content. A deviation from the intended shape is a problem for both the manufacturers and users of the final products and annually such deviations...
متن کامل16.4. the Mechanism of Moisture Movement during Drying
In the general form of the curve for the rate of drying of a solid shown in Figure 16.2, there are two and sometimes three distinct sections. During the constant-rate period, moisture vaporises into the air stream and the controlling factor is the transfer coefficient for diffusion across the gas film. It is important to understand how the moisture moves to the drying surface during the falling...
