Experimental study and CMFD modeling of transport processes in flow of two Immiscible liquids

Abstract

Rectangular shaped sieve plate column was installed for study of transport parameters through high speed photography and image analysis. Two Immiscible liquids consisting of the dispersed phase (water) and continuous phase (kerosene oil) were introduced in countercurrent operation. Experiments were performed for dispersed and continuous phase superficial velocities 0.16-0.44 cm/sec and 0.37-0.47 cm/sec respectively, pulsation frequency 0.95 -1.72 rev/sec and pulsation amplitude 1cm. Upon increasing the superficial velocity of dispersed phase, its void fraction increases up to its asymptotic value and droplet velocity increase while the droplet size decreases. Upon increasing the pulsation frequency, its void fraction increases while the droplet size and droplet velocity decreases. A Computational Multi Fluid Dynamics simulation has been carried out in order to verify the experimental results using the FLUENT. The CMFD calculations for void fraction have been compared with the experimental results which have shown a maximum deviation of 2-3%.
