Hi
I am going to analysis behavior of the water in the Jet condenser. I have meshed the model but in the Fluent after 700 iterations I see the "Reversed Flow in 8 faces on pressure outlet 9"


I increased the nomber of meshes up to 1500000 cells but the reversed flow did not remove. Please help me how can I omit the reversed flow in iterations? I choose the K-e, RNG method for turbulent flow.


Regards
Hamid

Reversed flow does not necessarily mean error, however it is hard to prove it.

You could extend your outlet till a region where there is no recirculation and hence no reversed flow.
