Abstract
Several correlations from the literature for frequency, liquid fraction in the liquid slug and translational speed in slug flow were adapted and compared with experiments with shear-thinning fluids. New correlations were proposed to describe the data obtained. The closure equations were incorporated into two mechanistic models of slug flow, and the impact of the change in each expression was analysed. With the modified models, it was possible to obtain errors of less than 20% in the prediction of the pressure loss for flows of non-Newtonian fluids.
