Hello everybody,

At the inlet of a pipe, I would like to control the fluid volume fraction of an air-water flow over time.
The multiphase model is here VOF.

For example :

When t = [0 ; 10] s : the fluid at the inlet is water (Water volume fraction = 1 ; air volume fraction = 0).

When t = [10 ; 20] s : the fluid at the inlet is air. (Water volume fraction = 0 ; air volume fraction = 1).

When t = [20 ; 30] s : the fluid is again water (Water volume fraction = 1 ; air volume fraction = 0).

And so forth...

Please, can you tell me what can I do to solve this case ?

Thank you in advance.

Gwen.

Do you have any idea or don't you understand my problem ?

Maybe I'm not clear enough !

Thank you.
