mutiphase flow and flow splitting

mutiphase flow and flow splitting

mutiphase flow and flow splitting

(OP)
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.

RE: mutiphase flow and flow splitting

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.
