PIV experimental study on the flow field in the rotor zone of an annular centrifugal contactor

- We measured the flow field in the rotor of ACC with PIV technique.
- Flow field with different rotational speed and flow rate were tested.
- The rotational speed had a significantly impact on the velocity.
- The flow rate had less effect on the tangential velocity and radial velocity.
- Vortexes formed in the rotational reference frame demonstrated CFD simulations.
