How to model Double-Pipe Heat Exchanger in Python
Steven He
I want to make a dynamic simulation of the heat exchanger. How to define the model?Thank you very much.

Steven,
I’ve attached an example of a heated rod (distributed parameter) system in Python (or MATLAB). You can run it by unzipping the folder and running main.py. The heated rod example could be adapted for your application where the heated rod would become the “wall” equation and you’d just need to add the fluid equation.
Another example of a distributed parameter system is the Solid Oxide Fuel Cell example in Python (and MATLAB). You can download it from http://apmonitor.com/do/index.php/Main/SolidOxideFuelCell but it is significantly more complicated than the example you proposed. It has spatial discretization two dimensions along with the typical time dimension for the dynamics. There is reaction, mixing, and heat transfer.
Best regards,
John Hedengren

Hello everybody,
I am trying to model double-pipe heat exchanger in Python. Section 2.4.8 Distributed Parameter System(the Double-Pipe Heat Exchanger) in Process Dynamics and Controll by Seborg.
Equations of the heat exchanger
