“…), and some of them are also applied in determining the thermal conductivities of wood and wood-based materials. For example, Houngan et al (2015) determined TC of two tropical wood species using dynamic TLS method. Maeda et al (2021) determined TC using the dynamic (TPS) method in samples of wood species originating from China.…”

The increasing use of wood leads to the need for a better understanding of its thermal properties with the aim of quantitatively identifying the exchange of thermal energy between wood and the surrounding solar radiation as precisely as possible. Reliable and rapid measurement of thermal conductivity is one of the most important current industrial requirements. The aim of this study is to examine the validity of using the modified transient plane source method (MTPS), which uses the principle of one-sided heating of the sample, and is defined by the ASTM D7984-21 (2021) standard, for determining the thermal conductivity of complex biocomposite composite materials such as wood. The analysis of the available literature shows a lack of data on the thermal conductivity of the type of wood originating in Croatia. In this study, the thermal conductivities of beech and fir wood samples in the longitudinal direction was determined by the MTPS method depending on the temperature and moisture content in the samples. Measurements were made on samples with a moisture content of 0%, 10%, and 20% in the temperature range from 20 to 80 °C.

The anisotropic bers of wood will lead to a macroscopic anisotropic property in both mechanical strength and heat transfer. Previous experimental studies of wood materials were mainly focused on the mechanical property while their anisotropic thermal property is still lacking. In this research, the anisotropic thermal performance of spruce wood is studied at different temperature, humidity and mechanical load. The one-dimensional steady-state method and the transient plane source method are adopted to conduct the test. The thermal conductivity both in-plane and outside-of-plane of spruce wood at temperature ranging from 25 to 422 ℃, relative humidity ranging from 30-90% RH and mechanical load ranging from 0 to 20 MPa are obtained. The accuracy of the TPS method is validated using the 1D steady-state method. Both methods can be utilized to gauge the anisotropic thermal conductivity of spruce wood. Due to the unidirectional distribution of ber, spruce wood has an outside-of-plane thermal conductivity that is roughly three times greater than its in-plane thermal conductivity. Among environmental conditions of temperature, humidity and mechanical load, the thermal conductivity of spruce wood are varied with temperature more signi cantly, which is followed by humidity and mechanical load. The measurement uncertainty is also discussed.
