Hello,
Can anyone explain the applicable flow correlations for horizontal two-phase flow?
I just need a starting point for my assignment.

ahaayoub,
Flow correlations for horizontal and inclined 2-phase flow are:
1. Beggs & Brill (frequently used)
2. Eaton for Holdup and Oliemans for frictional pressure loss
3. Hughmark & Dukler
4. Lockhart & Martinelli (for laminar flow only)
5. Flanigan
Regards,
Ankur.

Ahayoob,
On & above Mr. Ankur has suggested following correlation methods used for two phase (VL) flow calculations
1. Aziz, Govier & Fogarasi,
2. Baxendell & Thomas,
3. Duns & Ros,
4. Gregory Aziz Mandhane,
5. Hagedorn & Brown
But HYSYS is useing Beggs & brill method by default. This is one of the most accurate method.

ahaayoub,
Beggs and Brill method for horizontal flow. Hope this helps.
Find attachement.

1. A starting point could also be a Chemical Engineering reprint on the subject, such as http://www.che.com/articles/1985-1999/Vol102/chevol102_num6_162.html. I had used a previous reprint (~ 1979), titled "Chemical Engineering aspects of two phase flow", where concepts and correlations of two phase flows (horizontal and vertical) were presented.
2. A comment on post No 3: Method of Lockhart and Martinelli is not applicable to laminar flow only. We first calculate frictional ΔPs that would arise if either phase (liquid, gas) flew alone in the pipe. Depending on nature (laminar, turbulent) of each supposed single phase flow (liquid, gas), a multiplier is determined for the frictional ΔP of two phase flow. See J M Coulson - J F Richrdson "Chemical Engineering", Vol 1 (Pergamon 1977), Chapter 4 (Flow of Compressible Fluids and Two-Phase flow); also Perry, 7th edition (1997), Fluid dynamics, Multiphase flow (p. 6-26).
