I would like to evaluate the behavior of air bubbles passing through water passageways in a Francis turbine. When the bubbles enters the spiral case, they are under 130 meter of pressure. When they are passing through a distributor the flow velocity will increase and the corresponding pressure will decrease, so I wonder what kind of changes will experience them. Is it possible to simulate this phenomenom using CFX?
