Recently, a new chemical extraction method using Taylor-Couette vortex flow (T-CVF) is expected, because the extraction agent's contact and dispersion efficiency can be improved by use of T-CVF. Using this method, the amount of solvent and extraction agent can be reduced compared with the conventional methods, and environmental degradation and cost reduction are expected. For realizing the practical usage of this method, it is important to investigate T-CVF characteristics with axial flow including the inlet and the outlet. Therefore, in this study, we investigated the effects of axial flow on T-CVF structure using an Ultrasonic Velocity Profile monitor (UVP) can measure flow dynamic characteristics. From the measurement result, in the case with axial flow, the lift up phenomenon of T-CVF was confirmed.
