This article aimed to illustrate the Transient plane source (TPS) method’s abilities in measuring the local thermal conductivity of metal foams and detecting their in-homogeneities. A method was used to measure the effective thermal conductivity and thermal properties of powder metallurgical (PM)-aluminum (Al) foams, infiltrated aluminum foams, and PM-Zinc foams. The accuracy of the TPS method was then verified in the determination of defects or density in-homogeneities....
The present study used the transient plane source (TPS) technique to measure the thermal conductivity of a series of AlSi7 metal foams prepared by the powder metallurgical route. The main difference between the different foam samples was their density, which led to a change in thermal conductivity. In addition to measuring thermal conductivity, the TPS sensor was used to detect in-homogeneities by placing it on each face of a cube ...
Through the use of the transient plane source method the researchers were able to measure the thermal conductivity of a collection of cellular metals as well as the in- homogeneities of the samples. The volume of the samples was varied and the density of these individual volumes was calculated from tomography....
