Hi
I have a question regarding modeling an air-air heat exchanger I hope you can help me with. I have a serpentine flow pipes and a box for the air forced convection. I started with a very simple physics, non-isothermal flow. It converges but looking at the velocity profile, it looks like the pipes are invisible for the air flow. what I expect is a significant increase for the air velocity as the area decreases between the pipes.
also I can not choose the pipes boundary to add convective heat flux. I attached my model here. I appreciate if you could give me some tips.
Best Regards,
Elham
