i am working i\on bubble column reactor, i need to calculate bubble diameter for some purpose.
so how do i need to calculate it
what are the different equations that are to be taken into consideration,
Hi
I have never worked this problem myself. Perhaps you can find something useful in the enclosed PhD thesis or in this book by C.R. Brennen.

A small footnote. I was making some meaurements on a vertical tube, about 2 km long containing two liquds + gas where bubbles were evident in my measurements.
Much to my surprise, I found that the bubbles both to drive pulsation and be affected by pulsation. Bubble size changed once acoustic modes became evident.
Sincerely
Greetings,
In the mass transfer book of Traybal there is a full chapter (chapter 6, 2° ed) dedicated to estimate bubble diameter, mass transfer coefficients, liquid flow effect on bubble diameter, etc. These equations are basic bat could help for estimations.
Greetings,
This paper may help you, with best luck.
