Highly porous cellular materials capable of absorbing, emitting and scattering radiation are finding use at low and high temperatures in a range of traditional and modern technologies. The motivation for use of cellular materials is attributed to the high volumetric heat transfer rate (i.e., large surface area to volume ratio, high volumetric heat transfer coefficient), and large mixing rate due to the tortuosity of open cell foams. A brief overview of simulating heat transfer in cellular materials is presented and most important modeling parameters are identified, but the focus of the discussion is on heat transfer in cellular materials in the presence of radiation environment. Several examples involving radiation, conduction and radiation as well as convection and radiation for different technological applications are discussed, and the models are assessed by comparing the predictions with experimental data.

Highly Porous

Measurements of air filtration rate through the highly porous cellular materials in the presence of heating a porous material were carried out. A new measurement technique was developed and data of the dependence of the filtration rate of the temperature of air passing through the porous material were obtained with different pore size and in wide range Reynolds number. The experimental data were compared with the results of numerical modeling of the airflow in the porous samples, based on skeletal model of the cellular-porous material.
