CFD in a partially filled pipe

[Anonymous]

Hello to all readers,

I am fairly new to CFD Motion and I have to analyze the influence of assemblies in a partially filled pipe for a study project.

So basically I created a Model in Autodesk Inventor and imported it into CFD Motion. I am already able to simulate a constant flow through the pipe with the boundary conditions velocity (inlet) and pressure = 0 (outlet). Furthermore i saw the feature free surface which might be interesting for me.

My question is: Does anybody have experience or any kind of tips on how to simulate a partially filled water-flow in a pipe with CFD-Motion?

Thanks for your attention. Hopefully has a thought-provoking impulse for my brain.

Hey,

This would be very similar, but the inlet would be smaller, to represent the water level.

I suggest you run a 1/2 symmetry model as you are going to need a lot of mesh too.

Check out the free surface guide here.

Thanks,

Jon
