AbstractAbstract
[en] Pressure drop and heat transfer in porous media with inherent heat source were investigated in this paper. A new correlation for the flow pressure drop in the pebble bed was concluded and the experimental results for pressure drop obtained in this paper agree well with the correlation equation. The variation between the actual pressure drop values from the different correlations is quite considerable. The narrow range of system geometry as well as operating parameters of the existing correlations may be one of the main reasons why the predicted results are so scattered. The empirical correlation of heat transfer for porous media packed with heated spherical particles is derived from the experimental data and shows a well prediction. There are considerable discrepancies between the predicted Nusselt number calculated by different correlations that demonstrate more experimental studies needed for porous media with inherent heat source
