Hi!
Currently I`m trying to make an analysis in FLUENT 15.0 where I have a pipe with one inlet (12in diameter), a length of the total pipe of 10 ft, and at the end the pipe it has 4 pipes with a diameter of 4in. The fluid is air and I know flow and also I know the pressure at pipe inlet. The pressure at outlet pipe I do not know it and I want to know the pressure drop. When I insert information for boudary condition, I only have parameters like velocity inlet, mass inlet, pressure inlet but at the end I do not have mass flow outlet or velocity outlet or parameters like this. I have tried to find out how to solve it because the my idea was to put as an inlet boundary condition the inlet pressure and the outle boundary condition the mass flow outlet but ansys 15 does not have it.
Do you have any idea to solve the problem not involving outlet mass flow or outlet velocity flow?
Thanks
