air content in cfx post processing
Hi all,
can anyone help me with finding the amount of air content or concentration in fluid?! in post processing part .
thanks friends

Do you mean mixed at a micro-scale (ie bubbles)? Then you can see it as the air volume fraction in a multiphase simulation.

Do you mixed at a molecular level (ie air dissolved in water)? Then you can see it as the air mass fraction in a multi-component simulation, or possibly as an additional variable for a simpler approach.

thank you very much Glenn, as always,
not mulecular, and maybe bubbly!
I ment in air entrainment like as self aeration in water jets, I need the concentration of air content in the water.
I hope I could clarify myself.
does CFX have such ability?
thanks again

If the air is in bubble then you have a multiphase model. And the air content will be the air volume fraction.

Yes, CFX has many multiphase models. It is just a matter of choosing the correct one for your application.
