I have an air-water inside a cylinder as shown in the figure below. Red area is the air and blue is the water. The wall (grey in color) is rotating; wall. I want to figure out the transient behavior of air-water mixture inside this domain. Some of the key observations I have are:
1. Wall is not symmetric so I cannot give the wall a rotating velocity (rad/s). Isn't that true!
2. The problem can be solved by giving the mesh motion. But the question is will it capture the transient of the whole process?
3. Is there a better modeling approach for the whole problem!
