Abstract
The present work has the main objective of validating a unit cell model against experimental data for total pressure drop available in the literature. For this purpose, a horizontal slug flow with shear-thinning liquid is studied. Additionally, the performance of the model implemented in this work is also evaluated in comparison to other model taken from the literature. Two-phase gas/shear-thinning liquid flows are often encountered in oil and gas industries. Nevertheless, only a few research in the literature have focused on gas/liquid flow in which the liquid has a non-Newtonian behaviour. The pressure drop is one of the main parameters in hydraulic transport, and its evaluation is beneficial for equipment design. The unit cell approach is a mechanistic model that consists of performing mass and momentum balances across an assumed intermittent length. Several numerical simulations were performed for a wide range of superficial velocities and three different carboxymethyl cellulose solutions. The predictions of the mechanistic model were validated against the experimental data taken from the literature. The model predicts the total pressure drop with better overall performance than the literature model .
