The single and two‐phase flow field of a rotating disc contactor (RDC) extraction column is simulated with the help of computational fluid dynamics (CFD). The simulations were validated by particle image velocimetry (PIV) measurements. The single phase setup was used to test different turbulence models, and a 2D and 3D grid approach. For the two‐phase simulations, a 2D computational grid and the Euler‐Euler model was used. The two‐phase PIV measurements are possible when using an iso‐optical system, where the refractive indices of both liquid phases are identical.
