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
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...
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
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...
