You could plot contours of volume fraction showing walls to highlight the level of liquid along the walls.

You can also create a clip plane (z - plane) in the middle (along the axis of your pipe) and plot the volume fraction contours on this plane. This will highlight the level of liquid at the center if the pipe.

About the BCs, maybe share screenshots of your boundary condition panels?

I hope this helps.
