摘要

This paper proposes the two-dimension-two-velocity model for void fraction of gas-liquid two-phase flow. The model has considered the slip between the gas -phase and liquid phase, and the distribution of void fraction and velocity along cross-section area. The correlation between void fraction and volume fraction is obtained for adiabatic flow. The calculated results agree well with the experimental results.
