Investigation of Hydrodynamic of liquid–liquid extraction system in presence of TiO2 nano-particles

The main objective of this paper was to study the effect of the presence of nanoparticles on hydrodynamics of liquid-liquid systems. To perform this research, TiO2/water was used as nanofluid. Experiments were carried out in water-toluene system at two different weight percentages of TiO2 nanoparticles, 0.5 and 1.0 wt. % concentrations in water. According to the results obtained, it was observed that in nanofluid with 0.5 wt. % TiO2 concentration, drops were smaller but jet lengths were higher in comparison to the base fluid. In contrast in nanofluid with 1 wt. % TiO2 concentration, drops were larger and jet lengths were lower. These results were accepted with CFD model.
