Abstract
Unidimensional models are widely used in oil & gas industry to predict pressure drop and volumetric fraction, especially for horizontal stratified liquid-liquid flows. One limitation of these models is the good representation and accuracy for cases when drop entrainment is important. In this context, this work merges a unidimensional model (Rodriguez and Baldani, 2012) with entrainment parameters (Hadžiabdi´c and Oliemans, 2007) and a correction of wetted perimeters for each fluid phase in order to obtain a model capable of predicting pressure drop in stratified flow with mixture on the interface. This new approach is evaluated against experimental data and a well-established unidimensional model. The results show that the new model is capable of minimize errors and obtain better predictions for pressure drop .
