Abstract

Abstract: The time-dependent liquid film thickness and pressure drop were measured by using parallel
-wire conductance probes and capacitance differential-preesure transducers. Applying the
eddy viscosity theory and an appropriate correlation of interfacial sear stress,a new two-
dimensional separated model of holdup and pressure drop of turbulent/turbulent gas-liquid
stratified flow was presented. Prediction results agreed well with experimental data.

Key words: gas-liquid two-phase flow, stratified flow, holdup, pressure drop, model
