Abstract: Using the TPS method, the authors measured the thermal conductivity and thermal diffusivity of samples of Swedish wood. They also looked at the effect of density, porosity and anisotropy on the measured thermal properties. Both longitudinal and transverse measurements were taken at temperatures ranging from 20°C to 100°C and an increase in temperature resulted in a slight increase in thermal conductivity. The types of mechanisms that lead to heat conduction were explored, including voids and cell boundaries in the wood.
