Numerical study on drop formation in single hole in solvent extraction

چکیده
In the present study, computational fluid dynamics (CFD) simulation were performed to investigate the drop formation in single holes in a solvent extraction. The effects of various operating and design parameters on the drop formation were investigated in order to optimize the drop formation. Simulation results indicated that CFD simulations can give useful information about the drop formation in sieve plates. According to the numerical results, clearly different drop formation periods were detected. These periods were essentially different for the straight and conical holes. Furthermore, it was shown that the shape of the hole have considerable effect to the size of the drops formed. The simulation results were verified by comparison to experimental observations obtained using high-speed video technology. The numerical results of the drop shapes and detachment times were found to be consistent with images of experimental drops across a wide range of solute volume flow rates.
