Hello, everyone!
I am doing research on pool scrubbing and I am looking for experiments where a gas (preferably non-condensing) is injected into a pool by a single nozzle. I thought I could create an analogy with bubble column reactors (BCR) in chemical engineering however all the experiments I found are using some sort of sparger. How do you call the single nozzle BCRs in chemical engineering?
I need interfacial area concentration, a void fraction (gas hold up), and bubble as velocity information in a setting where the gas is being injected through a single nozzle into a pool or a large diameter tank. Any suggestions would be welcomed.
Thank you,
EB
I'm not a specialist in chemical engineering, but I have searched about shear stresses caused by bubble impact before, for my personal interest.
To me, it seems like there is no special term for a single nozzle BCR.
For example, see Esmali et al., Phys. Rev. Fluids, 2019 on bubble impact on tilted plate, Liu and Hu, Chem. Eng. Tech., 2004 on chaotic bubbling of bubble column... Both of them didn't use special terminology for the single nozzle BCR, but just called them 'glass needle' or 'single nozzle bubble column.'
But how about trying 'bubbling jet'? I could find a few papers written by M.Iguchi with the keyword, although he was the only one to use the term, as far as I know.
Sorry for my short of knowledge, but hope this could help you.
You could try "bubble plume" or "axi-symmetric bubble plume" or "point source bubble plume". At least that what it is called in two-phase flow (without reaction).
