Abstract

This study presents an experimental investigation on pressure drop in liquid-liquid Taylor flow regimes with the objective of extending previous research carried out on this topic. Pressure drop measurements were obtained over a wide range of Capillary (2.9 × 10−4 ≤ ca ≤ 5.1 × 10−2) and Reynolds (0.17 ≤ Re ≤ 45) numbers while carrier to dispersed viscosity ratio (µ ) spanned from 0.059 to 23.2. Five different liquid-liquid flow combinations were examined within capillaries of diameter 0.8mm. Analysis of existing models from relevant literature reveals that they are limited to specific ranges of Reynolds and Capillary numbers and not sufficiently accurate to predict pressure drop values over a wide range of viscosity ratios. Through comparison with experimental data from this study, the strengths and weaknesses of these models are identified and a more fundamental understanding of predicting pressure drop in Taylor flow regimes is developed.
