THE DRYING OF RED OAK AT VACUUM PRESSURE

The defects can be reduced, compared to that of traditional drying, by vacuum drying of red oak. In this work we present a mathematical model to predict the red oak wood drying kinetics. The mathematical model considers molecular diffusion and two-dimensional flow of humidity. The experimental work...
