Hi every one
I want to model flow inside the reservoir, with one inlet and outlet the inlet of my reservoir is connected to the Specified pump so my pressure and flow rate are known, I use fluent software, for modeling the inlet boundary condition I have two options velocity or pressure inlet Bc with velocity inlet bc, I have correct flow rate but my pressure is incorrect, and when I use pressure inlet bc I have correct pressure, but this time my flow rate is incorrect, So what can I do????? and what is the best boundary conditions for reservoir inlet???? Thank you |

this has always been an issue in fluid flow simulations!
sometimes tuning the outlet pressure boundary condition can help. |
