Hello Dear All,


I tried 2 different simulations for the same boundary conditions.


One of them was included solid body (Heat Exchanger) to do conjugate heat transfer analysis. I got my results.


then, I wanted to try only for fluid domain to compare with conjugate heat transfer analysis's results.


I did not change any boundary conditions, just I suppress my solid body which is around my fluid domain. then I started simulation.


When I obtained the results coming from fluid domain analysis,


I saw there are differences for Pressure Drop, Friction Factor, Average Wall temperature, and Nusselt number.


I was expecting, it should give the same results with Conjugate heat transfer analysis.


Do you have any idea why I could not achieve this?
