Bubble column

Please login with a confirmed email address before reporting spam

Hi everyone,
I want to create a geometry which is a straight cylindrical pipe with openings(ie., 9 circular holes) provided as inlet to the cylindrical pipe.The purpose is to simulate a bubble column for air-water. The circular holes are inlets for air, please
Can anyone suggest how to make openings and what physics to use(level set or phase field)?

Thanks in advance

Davinchi
