Hi all,

I'm new to fluent. I'm doing assignment on heat transfer analysis on a heat exchanger using porous method.

The bc are velocity inlet and pressure outlet in both cases ( i.e auxiliary and primary fluids ).

Now how do I calculate the outlet temp of both auxiliary and primary fluids?
Should I use mass weighted or Area weighted Average for finding out the temperature ?

Because both the values are different.

Please help.
Thanks in advance .
