A new model for wetting and drying of wood end-grain – with implications for durability and service-life

IRG/WP 11-20477

L-O Nilsson, K Sandberg

New experimental data for wetting and drying of wood end-grain, Sandberg (2009), imply that traditional models for moisture transport are not at all applicable. A new model is developed to consider the phenomenological behaviour of water transport in and out of end-grain, using the pore water pressure and sorption scanning properties. Modelling results are compared to experimental results and the consequences for durability are discussed.
