Numerical investigation of moisture movement in wood under isothermal conditions
The present work summarizes the results of several previous studies on moisture movement in wood during drying under isothermal conditions. A model of the wood drying taking into consideration coating of the surface of a specimen is presented in three‐dimensional‐in‐space (3‐D) formulation. The infl...

| Summary: | The present work summarizes the results of several previous studies on moisture movement in wood during drying under isothermal conditions. A model of the wood drying taking into consideration coating of the surface of a specimen is presented in three‐dimensional‐in‐space (3‐D) formulation. The influence of the geometrical shape as well as surface coating degree of wood specimens from the northern red oak (Quercus rubra) on the drying dynamics is investigated. The conditions of usage of 2‐D moisture transfer model in contrast to 1‐D for accurate predicting of the drying process are described.
Drėgmės judėjimo medienoje izoterminėmis sąlygomis modeliavimas
Santrauka
Šiame darbe yra apžvelgiama keletas ankstesniu darbu, kuriuose buvo nagrinejama dregmes judejimas medienoje džiovinant ja izoterminemis salygomis. Straipsnyje yra pateiktas trimatis medienos džiovinimo modelis, kuriame atsižvelgiama i galima bandinio paviršiaus izoliavima. Bandinio geometrines formos bei paviršiaus izoliavimo lygmens itaka džiūvimo dinamikai yra ištirta bandiniams, pagamintiems iš šiaures ažuolo (Quercus rubra). Darbe yra išanalizuotos salygos, nusakančios, kuomet yra tikslingiau naudoti dvimati modeli vietoje atitinkamo vienmačio modelio.
