     View Summary

    <p>To improve the performance of an annular centrifugal contactor with high throughput and separation performance, the effect of operating conditions on fluidic and dispersion behavior was investigated by computational fluid dynamics (CFD) analysis based on the turbulence model, and the calculated results were validated by experimental data. The liquid phase in the annular zone was gradually divided into two regions vertically with increasing rotor speed and decreasing flow rate, and a liquid flow toward the center of the housing bottom was generated in the lower annular zone under all operating conditions. The droplet size of the dispersed phase in the annular zone decreased with increasing rotor speed and decreasing flow rate. These calculated results showed good agreement with the experimental data. CFD analysis taking into account mass transfer between aqueous and organic phases was also attempted, and it was confirmed that the change in extraction performance with rotor speed showed the same tendency as the experimental result.</p>
