A simple model for predicting the pressure drop and film thickness of non-Newtonian annular flows in horizontal pipes
TL;DR: In this paper, a model of two-phase non-Newtonian horizontal annular flows, which predicts film thickness and pressure gradient from flowrates only, is presented, and the difference between the analytical model and the experiments is lower than 10%.
