Betreff: Heat Exchanger Model


Dear All,

for a research project we are looking for a detailed
fin and tube heat exchanger model.

Basically (copper or aluminum) fins are arranged to
enlarge the outside surface of (copper) tubes. A first
fluid (typically air) flows across the fins exchanging
heat with a second fluid (typically water) in the tubes.

Ideally such a model or type would calculate condensation,
pressure drop on the air side and take into account the
geometry of the whole device (such as fin thickness, space
between the fins, tube diameters...)

Probably some work was done to modify TRNSYS type 5.

Any help would be highly appreciated.

Thank you in advance,
Regards,
Matthias Bail
