Effective thermal conductivity of metallic foams determined with the transient plane source technique

Metal foams are materials composed of a solid grid with air-filled pores, and have applications in combustion chambers of gas turbines. In this study, the thermal properties of porous metal foams were tested to determine their usefulness in heating and cooling systems. The Transient Plane ...

Effective thermal conductivity of sintered metal foams: experiments and a model proposal

It is important that porous metal foams used in gas turbines do not exceed their upper temperature threshold. In this paper, the Transient Plane Source (TPS) technique was used to measure the thermal conductivity of metal foams up to 1000 °C. Results showed that the thermal ...

Macroscopic foam model with effective material properties for high heat load applications

This study used macroscopic equations to determine fluid dynamics and heat transport properties in metallic slip-reaction (SR)-foams for their application in gas turbines. The numerical results were validated by an experimental method that analyzed the physical and mechanical properties of the SR-foams. An apparatus ...

Effective permeability and thermal conductivity of open-cell metallic foams via homogenization on a microstructure model

This research article delves into the thermal conductivity monitoring of open-cell foams. The foams are created through an intense procedure, in which slip reaction foam sintering is employed. Prior to measuring the thermal conductivities of the foams, a multiscale approach, taking into consideration the homogenization ...

Porous materials as open volumetric solar receivers: Experimental determination of thermophysical and heat transfer properties

Previously, the thermal conductivity of extruded monoliths, ceramic foams and metal structures were determined for their application as open volumetric receivers in concentrated solar radiation. Volumetric receivers contain a porous material, which is ultimately heated through solar radiation. The pores allow ambient air flow through ...
