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 method, was used to predict thermal conductivity values. To obtain experimental results, the Transient Plane Source method was then used to determine the thermal conductivity ...

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 the material, which will eventually reach a temperature of 700˚C. This heat is then used to feed the steam turbine process. Understanding the effect of ...
