I have a model of a heat exchanger to simulate in Flow. Of course, the geometry of this model is big to be done by Flow or any CFD I think,
and some simplifications are required. What kind of the simplifications can I make? How can I simplified the tube bundle of the exchanger and not lost accuracy
on my results?
I see the tutorial of Flow Simulation regarding this kind of simulation but not mention how to get to that CFD model.
