mutiphase flow and flow splitting 1

[dcasto]

My colleagues and I remembered seeing a video, well an 8mm film, of a lab where they had glass tubes to show you what happens in multiphase flow.

One of the most interesting was the split flow. When a two phase flow in a line comes to a tee branch the flow can go straight, or take a 90 turn, almost all the liquids took the turn at the tee. They would vary the split and sure enough, when 10% of the flow took the turn, almost 90% of the liquids went with the 10% of the gas.

We actually are seeing this. One engineer built a "unique" slug catching facility that had a tee arrangement in it. The 12" line had a tee branch It didn't work out quite right so the field just runs the 2 12" lines open all the time. Guess what, those 2 lines each have a separator and the separator on the line that took the 90 turn is always flooded and the dump valve cannot keep up.


The question is; has anyone else run across this old video, We'd like to give it to our field people to show them what is happening. I've looked at youtube, no luck.

Bob Welker at Welker Engineering used to present videos like the one you're talking about at the annual International School of Hydrocarbon Measurement (ISHM). I haven't been to ISHM in 10 years so I don't know if he's still doing it. You might look at the Welker Engineering web site.

This has some stills of glass manifolds, and a whole bunch of graphs:

Aside: I've messed with a bunch of wet exhaust pipes in boats, and nothing would surprise me now, including what you report.
