Abstract: Wood can be defined as a composite, porous material as it is effectively made of two different substances. This property is reflective of how differently the wood grows with respect to the four seasons and how the materials in the wood can change based on ambient heat. The constant change in seasons therefore forms wood grains, which show the differing thermal properties of wood material. This paper finds the apparent thermal conductivities of slabs of wood with the graining at different angles to the faces of the slab by the transient line source technique. It is also discussed how different species of trees have different porosities and how that effects the apparent thermal conductivity.
