The heat transfer was modeled with a thermal contact resistance between the hot and the cold channels. The momentum sources were related to the Fanning friction factor, which in turn was related to the Reynolds number by experimental correlations provided by Alfa Laval.
To account for the effect of the corrugation on the pressure drop, one-time pressure losses and momentum sources were added in the model.

The full geometry of the channels has not been included, the channels were modeled with a flat geometry instead of a corrugated pattern.
