摘要

The instability of a liquid-gas interface in countercurrent annular two-phase flow is studied with a small disturbance analysis; the curvature of the interface and the viscosity and velocity distributions in liquid and gas phases are necessarily taken into account. This analysis indicates that the average velocity, velocity distribution, and viscosity of liquid film affect the instability criterion significantly. Comparison of the present analysis with analyses by Hewitt and Imura, in which the viscous effect was neglected, indicates that viscosity produces two critical boundaries that indicate stable and unstable regions instead of the one boundary predicted in existing analyses.
