摘要/Abstract

摘要： Zero net-liquid flow (ZNLF) is a special case of upward gas-liquid two-phase flow. It is a
phenomenon observed as a gas-liquid mixture flows in a conduit but the net liquid flow rate
is zero. Investigation on the liquid holdup of ZNLF is conducted in a vertical ten-meter
tube with diameter of 76 mm, both for Newtonian and non Newtonian fluids. The gas phase is
air. The Newtonian fluid is water and the non-Newtonian fluids are water-based guar gel
solutions. The correlations developed for predicting liquid holdup on the basis of
Lockhart-Martinelli parameter are not suitable to ZNLF. A constitutive correlation for the
liquid holdup of vertical ZNLF was put forward by using the mass balance. It is found that
the liquid holdup in ZNLF is dependent on both the gas flow rate and the flow distribution
coefficient.
