Hysis discrepancy with two phase slugs
Hysis discrepancy with two phase slugs
(OP)
I'm using Hysis version 2006.5 and it appears that there's some contradictory calculations regarding slug flow. Using the slug calculation/prediction tool, it shows stable two phase flow. Great news! However, double checking with the flow regime map using beggs/brill or Aziz (horizontal pipe), it shows the 2 phase flow as slug.
What gives?

RE: Hysis discrepancy with two phase slugs
I recommend you confirm the flow regime using the methods (vertical and horizontal) of Dukler+Taitel. I have had a fair bit of success with them.
Their graphs are more difficult to use than others, but is avialable in some software programs. My biased opinion is to use Korf (www.korf.co.uk).

And at the moment we are adding support for Gas/Liquid Wells for a client (will be in next rev).
RE: Hysis discrepancy with two phase slugs
Right now I'm in the midst of a voting method where I look at the slug tool result, the Orkiszewski flow regime, the Gregory/Aziz/Mandhame flow regime and the Beggs/Brill flow regime results and taking the consensus.
If I go back to school for my masters, I'm pretty sure my thesis will be on 2 phase flow study. :-o
