I am trying to provide a constant heat flow source [THHS0-2] to a half heat exchanger.
Previously, I've been able to use the half exhanger [TFEX02-1] and had no issues. This is now considered an obsolete model now, but the new [TFEXSIMP01-1] model dosen't seem to like being used this way.
Has anyone been able to use the new model in this manner?
Solved! Go to Solution.
if you look at the external variables on the half heat exchanger, you will note that both the heat flux and the temperature are expected at the port 3 - it explains why you can't anymore connect a direct heat flux source on it.
You might use the submodel below - connect its port 1 to the port 3 of the half heat exchanger - and apply the heat flux targeted as an input signal at port 2.
Then, select heat flow rate [W] in the enumeration.
hope it helps
