Paper Number: BHR-2019-155
... 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...

... experimental condition and comparisons were carried out by varying only one parameter at a time (viscosity, superficial liquid velocity or superficial gas velocity). The criteria to decide on representative slug units was based the average slug length. The average slug length was analysed by two-wire...

Paper Number: BHR-2015-B1
... Accumulation of liquid, as oil and/or water, at the bottom of an upward inclined pipe is known to be the source of many industrial problems, such as corrosion and terrain slugging. Accurate prediction of the critical gas velocity that can unload the liquid accumulation is of great importance. An experimental...

... showed that both inlet gas velocity and inlet liquid holdup affect liquid distribution and holdup in the upper section of the separator. 1. INTRODUCTION 1.1. Liquid holdup in gas-liquid cyclonic separator During normal operating condition of a gas- liquid cyclonic separator, liquid can exist in the upper...

... and also a higher superficial gas velocity, USG, is needed to convert stratified to annular. Most importantly it has been noticed that the maximum drag reductions occur when the annular flow pattern changes to stratified or a slug to pseudo-slug flow pattern. The finding that the slug flow regime change...
