A model for predicting holdup and pressure drop in gas-liquid stratified flow

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