I am working on simulating a transient flow that is compressible and turbulent through a pipe. You can think of it like an explosion on one end of the pipe and I am trying to simulate the fluid in the rest of the pipe. I want to make sure I have my viscous model setup correctly. Can someone please give me some advice on the best viscous model to use? Thanks!

Hello mmorg41, below have a two references to you find the correct set up for turbulence model!

Obviously my ansert is a bit simplistic and a good read about turbulence would explain it better.
