A mechanistic model of heat transfer for gas–liquid flow in vertical wellbore annuli

Abstract The most prominent aspect of multiphase flow is the variation in the physical distribution of the phases in the flow conduit known as the flow pattern. Several different flow patterns can exist under different flow conditions which have significant effects on liquid holdup, pressure gradien...
