Abstract

Pressure drop and liquid holdup for a device with a relatively short vertical pipe operating at high gas velocity were experimentally studied.
An analysis of pressure drop and liquid holdup is carried out, using the principle of minimum entropy production proposed by S. M. Zivi, which includes the friction factor for annular two-phase flow and the correction factor for predicting total pressure drop. Correlations for these parameters are obtained empirically.
