The thermal properties of wood in the green state have been determined by the transient plane source (TPS) technique. Data are presented on thermal conductivity ( λ ), heat capacity ( C ), and thermal diffusivity ( κ ) at moisture contents (MCs) above the fiber saturation point, which are based on measurements using the HotDisk ® apparatus. Four wood species (Douglas fir, beech, birch, and spruce) were tested, and the results are compared with literature data and those obtained by the flash method. A linear relationship was found between the thermal properties λ , C , and κ on the one hand and MC on the other. Equations predicting the thermal values as a function of MC and wood anisotropy are presented. Wood C and λ increase with MC, but wet wood diffuses heat more rapidly than dry wood.< Réduire
