... ABSTRACT The present work investigate the effect of droplets entrainment on critical gas velocity, using the liquid film reversal model from Barnea (1986), Luo et al. (2014) and Shekhar et al. (2017). Especial attention was given to the onset of liquid loading in gas well. Experimental...

... entrainment and deposition have relevant impact on annular flow properties, such as pressure drop and film thickness, as vastly shown in literature. Several authors have described physical mechanisms for droplet entrainment and deposition; many of those are related to disturbance waves. The objective...

... at 20 and 90 bar pressure. Results and implications from these measurements are discussed. Next, a detailed model for droplet entrainment is presented. The experimental data is analysed based on the proposed model framework and the model is calibrated using the available measurements. The subsequent...
