Hi guys I need your help
I'm investigating heat transfer in the presence of nanofluid with fluent 6.3.26.
This time I have no problem with the software! And the results have no meaning to me.
In the presence of nanofluid we can say we have always an increase in Nu and Pressure loss, but fluent say something completely in reverse!
I used many solutions like changing the multiphase model, searching for an optimum nanoparticles concentration or diameter and so on.
Could someone help me, I don't know what is the problem with my case?
Any help will be appreciated.
