Hi all,

 

Is there any specific criteria to count a stream as a two phase ( consideration mainly based on fraction of a fluid in a flow or stream)? Like if in a stream there is 0.96 or 0.99 or 0.91 or 0.80 or 0.995 of vapor fraction, should we assume that is a two phase/multiphased stream?

Thanks Breizh.

Yet in that IPS, couldn't meet the query as I hope so. If I understand, there found only the calculation procedure for single phase or multiphase flow.

If a gas stream contains some liquid drops then it is in principle a two phase flow.

 

However, whether that matters depends on what that (wet) gas is to be used for. A small amount of liquid drops will hardly affect the line pressure drop, but they could cause erosion in control valves, or disrupt the operation of solid beds for removal of gas impurities, or ........

It seem that you query about how to determine the flow regime for two phase flow. You can google "Mandhane flow regime" and may find some useful information. You may also look at GPSA data book for the two phase flow pressure drop calculation
