【摘要】 本文提出了二维二速度气 液两相流含气率模型,模型考虑了两相间的滑移及含气率和流速沿流通截面的分布,对绝热流动情况下推导出了截面含气率与容积含气率之间的关系式,模型计算结果与实验结果符合较好。更多还原

【Abstract】 This paper proposes a twodimensional twovelocity model for void fraction of gasliquid twophase flow. The model has considered the slip between the two phases, and the distribution of void fraction and velocity along the crosssectional area. The correlation between void fraction and volume fraction are obtained for adiabatic flow. The calculated results agree well with the experimental data.更多还原
