Hi all,

I hope you all are doing well!
I am wondering if the porous media coefficients will change if the working fluid changes.
I have a tubular, U-shaped heat exchanger geometry where the working fluid is air.
This model has been tested (experiments) in detail earlier, and its porous media coefficients have been estimated.
Now I need to use the same heat exchanger geometry (for CFD), but the working fluid is replaced with water.
Can I use the above porous coefficients for water?
Kindly make your replies.
Thanks in advance.

Hi all,

Please, if anyone has experience related to the above, kindly suggest something.
Sorry, but I am running out of time.
