Conjugate, non-isothermal u-pipe, time-dependent study

I wanted to simulate the heat transfer of fluid in a u-pipe. However, I'm really confused about which module and model should I use?

Initially what I wanted to do is to choose the heat transfer in porous media modulue, however, I found difficulties of solving the problem of directing the fluid from vertical pipe into u-shaped corner by defining a velocity. Based on my shallow experience with Comsol so far, it seems that this modulus only allows the fixed velocity vector to be defined at the input stage, and I found it difficult to resolve for the model.

I have also tried to use the conjugate heat transfer as well as non-isothermal flow... then I started to get more confused because my analysis has to be carried in time-depenent study. Would anyone give me some advices?

Thanks for your advice in advance!

Hi
Indeed I would say that is a wise advice, but do not foret that, depening on your model, you do not always who is "master" and who is "slave" between flow and heat. So ending up with a fully coupled and pre-cooked Conjugated Heat Flow model is good practice too

Good luck
