Heat exchanger model

Dotti Massimo

I'm trying to set on the heat exchanger module described in § 6.23 . I checked m * cp for air being lesser than m * cp for coolant, set into the model a good amount of hot air, let it pass through the exchange region but nothing happens. The porous behaviour of the region were set on automatically, but no heat exchange ever occured. Do anyone had the same problem? Is there someone with a suggestion? Thanks Massimo
