I am trying to simulate the flow trajectories inside an HVAC system, but I am not sure about how to simulate the plate-fin heat exchanger. I have the geometry but it so complex with all the fins and I was thinking to consider it as a porous medium. I have the pressure drop curve. Initially I do not need to simulate the heat exchange, just the air movement through the coil.
What do you think? Do you have any experience simulating this kind of heat exchangers?
Thank you in advanced,
