Counter flow HX
Hello guys, I am trying to simulate a counter flow heat exchanger with known inlet temperatures and velocities. wall thickness is to be considered as well.
I am having a problem in setting the outlets bc. if i set them to pressure outlets i have to key in the outlet pressure which is one of the things i am looking for in this simulation.
one more problem is in the walls between the 2 fluids (the wall and the shadow wall)what is the best bc to be used here?.
I would really appreciate your help in these problems
