Lattice Monte Carlo and Experimental Analyses of the Thermal Conductivity of Random-Shaped Cellular Aluminum

The effective thermal conductivities of open and closed-cell aluminium foams are measured by numerical, analytical and experimental methods. These methods are represented by the Hit Disk method, computed tomography (CT) and thermal Lattice Monte Carlo (LMC) analysis. Furthermore, the report includes experimental measurements of open-cell-M-pore and closed-cell Alporas cellular aluminium. All the results are then compared....

Density gradients in aluminium foams: characterisation by computed tomography and measurements of the effective thermal conductivity

Through the use of computed tomography and the TPS method, the authors of this article were able to calculate local effective thermal conductivities of aluminium foams synthesized through the powder metallurgical route. Computed tomography was first used in order to measure the density of a given area of the sample and this density was then used in the TPS measurements in order to generate local effective thermal conductivity values....

An experimental study on the thermal conductivity of aluminium foams by using the transient plane source method

A collection of AlSi7 foams (porosities 0.5 to 0.8) were analyzed using the TPS technique in order to determine thermal conductivity. Increased density was found to lead to increased thermal conductivity. The TPS technique was found to be sensitive to the in-homogeneities created from the foaming process; therefore the foaming process is an important factor in the determination of thermal conductivity of a given foam. The authors also combined several theoretical models ...
