Hello,

I am trying to model a portion of a pump-driven flow in a pipe and I am not sure about its BCs. I set the Velocity Inlet for the inlet with a specific fluid velocity. For the outlet, I can choose "Pressure Outlet" BC, but it also ask for a temperature that I am not sure.

Can anyone advise on BCs of pumped flow (so the outlet is not zero pressure)!
Thank You.

In my opinion the temperature of the pressure outlet for an continous system isn't that important. The fluid flows out of your system and the heat-transport against your flow direction isn't significant.

In order to avoid bad residuals I usually choose the inlet temperature or the reference temperatur.

Actually I can't remember a tutorial case where the outlet temperature where really important for the results.
