Radiative properties of extruded polystyrene foams: Predictive model and experimental results

Numerical study of effective heat conductivities of foams by coupled conduction and radiation

“…(4). This description is richer than the usual correlations given in literature because it is found here that k + (or equivalently the scaled optical thickness) is a more complex function of emissivity and radiation/conduction ratio.…”

“…Polymer foams are used as insulators [2][3][4], metal foams as compact heat exchangers [5], ceramic foams as porous burners [6,7] or solar collectors [8][9][10], carbon foams as heat exchangers [11] or electrodes [12], especially for fuel cells [13]. Carbon [14] or metal [15] foams are used as a conductive network and as mechanical reinforcement for thermal energy storage materials, in combination with phase change materials (PCM).…”

Heat transfer in microcellular polystyrene/multi-walled carbon nanotube nanocomposite foams

“…This is due to the very low radiative absorption of low-density polymeric foams [22]. Therefore, it is essential to block radiation to reduce the total thermal conductivity.…”

Experimental characterization and theoretical modeling of the infrared-optical properties and the thermal conductivity of foams

“…Several models have been previously developed to characterize the thermal conductivity and the radiative heat transfer [11e16]. Some specific models for EPS [17,18] and XPS [19] have been developed to determine thermal properties from the microstructure.…”
