CFD: speed balance

My model represent a curved pipe, the fluid is uncompressible (water) and boudary conditions are: Inlet pressure and Outlet pressure. Internal diameter is costan, so the Income speed must to be equal to the Oucome speed.
I’m not a CFD expert don’t understand why Inlet and Outlet speed are so different 7%.

Hi @uprova,

Thanks for posting your question!
It is difficult to determine the exact cause of this discrepancy without more information about your model and simulation setup. Could you please share the project link here?


Hi again @uprova,

Just following-up, how is your project going? If you do need some help, please share the project link that would be a pleasure to jump into this.



thanks for your replies, I didn’t see them before. The project has been stopped.
