With the program AC finned or bare cross flow heat exchangers can be calculated. With the "free input" feature, you can enter physical properties of any media. Due to a special thermodynamic model, condensation processes (total and partial) are possible, both around and in the tubes.
Vaporization processes of pure substances in the tubes can also be calculated
