Dynamic moisture transport in spruce wood – Experiment in hygroscopic range under isothermal conditions

Popis výsledku v původním jazyce

The moisture behaviour of wood has been naturally studied since ancient times. Despite being commonly used in almost all industries, some of its moisture properties are still not precisely defined. Inaccuracies of the measured properties are reflected in numerical simulations and can lead to its improper use. Although the wood can often handle minor errors in its use, it will be beneficial to use it more consciously and efficiently in the future. Therefore, it is important to understand its moisture behaviour more accurately. This paper presents an experiment of dynamic moisture transport in spruce wood in high levels of ambient relative humidity under constant temperature. Only one-dimensional moisture transport in the tangential and radial directions were studied. The results show the rate of the stabilization of moisture content and the effect of sorption hysteresis under repeated cycles of the step changes of boundary humidity levels. The results can help to better understanding of the moisture behaviour of wood and to further improvement of some of the numerical simulation tools.
