 November 18, 2003, 07:15 transient natural gas flow in a single pipeline #1 Leila Guest   Posts: n/a Hi everybody I'm gonna model transient natural gas flow in a single pipeline. Is Fluent capable of modelling such kind of fluid flow? Is fluent powerful in the field of interior flows? How does it act upon compressibility? Please help me and let me now whether I'd better use Fluent for these purpose or not?

For compressible calculation in the material pannel, set the density to ideal gas. Please describe more about transient effects. For transient calculation you need to set unsteady in the solve pannel. Regards

But to answer your question, please define your case more clear and give more information, then I might be helpful.
