“…Therefore, the periodic boundary conditions adopted here are applicable and recommended because of the much lower computation time. Similar observations were made by Rieger et al [6] and Haderer [7]. Furthermore, a node spacing of 0.5 mm was satisfactory for the predicted velocity profiles.…”

“…Velocity fields in a single phase flow RDC were measured using a Laser Doppler Velocimeter (LDV) and simulated with CFD by Fei et al [5]. Rieger et al [6] investigated the one-and two-phase flow in a RDC extraction column employing an Euler-Euler and an Euler-Lagrange model, but experienced problems with convergence. Haderer et al [7] investigated different turbulence models for the one-phase flow and applied the Euler-Euler model for two-phase flow simulations.…”

“…Haderer et al [7] investigated different turbulence models for the one-phase flow and applied the Euler-Euler model for two-phase flow simulations. The Laser Doppler anenometry (LDA) velocity measurements conducted for validation by Haderer [7] and Rieger [6] did not allow a comparison of the whole velocity profile. As a result, only a few data points at rotor level could be compared.…”

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.

in Wiley Online Library (wileyonlinelibrary.com) Sustaining stable liquid-liquid dispersion with the desired drop size still relies on experimental correlations, which do not reflect our understanding of the underlying physics and have a limited prediction capability. The complex behavior of liquid-liquid dispersions inside a stirred tank, which is equipped with a Rushton turbine, was characterized by a combination of computational fluid dynamics and population balance equations (PBE). PBE took into account both the drop coalescence and breakup. With the increasing drop viscosity, the resistance to drop breakage also increases, which was introduced by the local criteria for drop breakup in the form of the local critical Webber number (We c ). The dependency of We c on the drop viscosity was derived from the experimental data available in the literature. Predictions of Sauter mean diameter agree well with the experimentally measured values allowing prediction of mean drop size as a function of variable viscosity, interfacial tension, and stirring speed.

“…Simulationen in gerührten Extraktionskolonnen wurden bereits von Modes [2], Fei et al [3], Rieger et al [4], Haderer et al [5] für RDC (rotating disc contactor)-Extraktionskolonnen und von Kolb [6] für eine Kühni-Kolonne durchgeführt. Bis auf die Arbeit von Kolb, der die Simulationen mit Particle Image Velocimetry (PIV)-Messungen validierte, wurden die Simulationen für den RDC nur mit LDA-und LDV-Messungen validiert, wobei der Vergleich der Geschwindigkeiten an diskreten Messstellen, jedoch nicht die Sichtbarmachung und der Vergleich der gesamten Strömung möglich waren.…”
