Predictions of effective thermal conductivities for three-dimensional four-directional braided composites using the lattice Boltzmann method

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 ...

A numerical study on the theoretical accuracy of film thermal conductivity using transient plane source method 

Currently, there is no research into the accuracy of the transient plane source (TPS) method for measuring the thermal conductivity of thin films. The purpose of this study is to use numerical simulation to determine the accuracy of thermal conductivity measurements of thin films, with the TPS method. The values produced from the TPS method closely resembled those of the numerical simulation. The deviations from the numerical model were caused ...

Influence of environmental factors on the adsorption capacity and thermal conductivity of silica nano-porous materials 

Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment was to determine how temperature and humidity affect the insulative properties of silica nano-porous aerogels. A thermal constants analyzer measured the thermal conductivity of moist silica nano-porous materials using the transient plane source (TPS) method. Results showed that the thermal ...
