Multiphase flows are frequently found in nature and industry. Depending on its geometry, those phases can present themselves in different patterns. Through pipes, there are the annular, slug, stratified, bubble patterns, etc. The present study focus is in the annular vertical flow, which is charac-terized by a gas core flowing in high velocity and a liquid film. Due to high gas velocity, liquid droplets can entrain the gas core and can also deposit back in the liquid film. This process can have a significant impact in the flow characteristics. Thus, the objective of this work is to analyze entrainment and deposition models in annular vertical flow through the 1D Two Fluid Model. Two combinations of models were selected to be investigated. The first one consists in Ueda s (1979) droplets entrainment model and Pan and Hanratty s (2002) for deposition, and the second one is a modification of these models, including a coefficient to concentrate theses phenomenon on the tip of the waves. The data obtained were compared to the literature and showed improved results with the modified models for the prediction of the liquid film height and in the frequency of interfacial waves.
