Hello,
On the official DWSIM user's guide there are several examples of ways DWSIM can calculate heat exchanger streams, but I couldn't find the calculation method through the "heat transfer efficiency". How it is calculated? I'm personally interested in the equation itself; is it just the temperature difference ratio like in the attached image?
Thanks in advance :)
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
The maximum heat transfer is estimated by checking the conditions of the inlet streams (temperature and flow), then the efficiency is multiplied by this estimate to calculate the actual heat transfer.

I have been able to view heat exchanger enthalpy plots/curves in the classic user interface only when using minimum pinch temperature difference as the method. Can you advise how to get this feature activated for other exchanger solution methods and in the cross-platform interface?
This feature is at the bottom of the heat exchanger object editor, with the caption "View Temperature vs Heat Exchanger Profile."
Thanks!

Hi Rick. I'm afraid it is not implemented for the CPUI. Please create a new feature request here: https://github.com/DanWBR/dwsim/issues/new/choose
