Modeling the physical processes relevant during hot pressing of wood-based composites. Part I. Heat and mass transfer

摘要: A three-dimensional model based on fundamental principles to simulate heat and mass transfer mat densification during batch or continuous hot pressing of wood-based composites is presented in this pair papers. The present paper gives a comprehensive description mathematical formulation the relevant mechanisms, which are water vapor air by gas convection molecular diffusion, conductive convective transfer, including sorptive effects. consists set constitutive flux equations that coupled local energy balances.
