Abstract
The effects on the measurement of water sorption and apparent diffusivity when using different flow rate values and different experimental setups, i.e., closed pan, open pan and hanging setup, have been studied in a series of Dynamic Vapor Sorption (DVS) experiments on a spruce sample. The results confirm a concave exponential growth dependency between apparent diffusivity and flow rate and an effect from the setup used, with the hanging setup being optimal for conducting such experiments due to the exposure of both areas of the disk to the airflow.
期刊介绍：
European Journal of Wood and Wood Products reports on original research and new developments in the field of wood and wood products and their biological, chemical, physical as well as mechanical and technological properties, processes and uses. Subjects range from roundwood to wood based products, composite materials and structural applications, with related jointing techniques. Moreover, it deals with wood as a chemical raw material, source of energy as well as with inter-disciplinary aspects of environmental assessment and international markets.
European Journal of Wood and Wood Products aims at promoting international scientific communication and transfer of new technologies from research into practice.
