The Transient Plane Source thermal constants analyzer stands out in the field of thermal conductivity testing equipment due to its ability to measure anisotropic materials. In this paper, the mathematical derivation of the equation used in the anisotropic software module of the TPS is used to calculate the thermal conductivity and thermal diffusivity of three Italian tree species; larch, oak, and spruce. Axial thermal conductivity was found to be much ...
The authors present a multiple-relaxation-time lattice Boltzmann model with an off-diagonal collision matrix for use in predicting the thermal conductivity of anisotropic heterogeneous materials with anisotropic components. Model accuracy was first confirmed through comparison with previous simulation results. In this paper the model was applied to measure the tranverse and longitudinal thermal conductivities of 3D4D braided composites. The TPS method was used to measure the conductivities experimentally for comparison ...
