Hello,

 

Is there a way to calculate the minimum velocity of a flowing gas needed to entrain a liquid?

• Falling liquid film on a vertical flat plate with upward flowing gas.
• Stagnant pool of liquid with horizontally flowing gas.

Are there maximum allowable values to prevent entrainment in these scenarios (rules of thumb)?

 

Thanks!

For separators, there are some published articles. Google Ken Arnold along with the subject.

Thanks for the help.  I found a book called "Gas-Liquid And Liquid-Liquid Separators" by Maurice Stewart, Ken Arnold.  For re-entrainment, the book suggests that the following paper should be consulted.  I looked up the paper using Onepetro and it solved my problem.
