Correlation between vessel features and hardwood drying properties; case study: beech (Fagus orientalis) and oak (Quercus castaneifolia)

In this research, the effects of vessel features, including vessel diameter, density and porosity on drying rate and casehardening of beech (Fagus Orientalis) and oak (Quercus castaneifolia) was investigated. For this purpose, flat-sawn boards with dimensions of 170×50×80 mm (L×T×R) were cut from th...
