Modeling the physical processes in natural fiber composites during batch and continuous pressing

Creator:: Thomen, Heiko
Abstract:: A three-dimensional model based on fundamental principles to simulate heat and mass transfer and mat densification during hot pressing of wood-based composites is presented. Mechanisms included in the analysis are water vapor and air transfer by gas convection and molecular gas diffusion, conductive and convective heat transfer, and sorptive effects,...

Numerical modeling and experiments on wood-strand composites

Creator:: Le, Edward A.
Abstract:: In wood-based composites, the glue-line (interface) between wood-strands affects the stress transfer from one member to the next. The glue-line properties determine the rate of load transfer between phases and these properties depend on wood species, surface preparation, glue properties, glue penetration into wood cells, and moisture content of the...

Numerical simulation of wood drying

Creator:: Berberovic, Adin
Abstract:: A mathematical and then a numerical model were developed for simulating a convective batch lumber drying process. The model incorporates mass and heat transfer relationships within the lumber stack, as well as thermodynamic properties of the wood and drying air. It takes into account a change of air properties along...

Dynamic modeling of thermal treatment of timber poles

Creator:: Sahle-Demessie, Endalkachew
Abstract:: The temperature-time-location relationships during steam conditioning and pressure treatment of timber poles have been studied and mathematical models that take into account both the thermal properties of the poles and the parameters of the treatment process have been developed. Although much work has been previously done in this area, the...
