Two phases flow

Please login with a confirmed email address before reporting spam

Hello,

I'm trying to simulate air injected from a 1.54 mm inlet into 15 * 20 cm water domain and the velocity is 0.045 m/s so bubble would form naturally and the surface tension = 0.072.

I am having problem with both phase field and level set the tuning parameters are not working correctly and also which one of them i use to perfectly capture the bubble diameter (level set or phase field)?

For the wetted wall i assumed pi/2 for all the domain or only the wall were air is flowing next to water?

In the photo the experiment I'm trying to validate

Appreciate any type of help!
