Information

1. Purpose of model

Heat Transfer Correlation for packed bed to adjacent air volume according to Bejan et al.

2. Level of detail, physical effects considered, and physical insight

The correlation is derived for a lateral fluid penetration due to natural convection into a porous structure from the side.

A weighting function is introduced in order to distribute the transferred heat to the different finite volumes inside the packed bed.

It need the penetration length as parameter, which thus has to be iteratively corrected.
