摘要
漂移流模型在两相流空泡率计算中处于非常重要的地位,长期以来,研究者对模型中分布参数及漂移速度的确定持不同的观点。本文采用理论分析与实验研究相结合的方法,总结了分布参数和漂移速度的一般规律,提出了垂直上升两相流漂移流模型分布参数和漂移速度必须满足的限制条件,根据理论分析以及实验数据的验证,得出了漂移流模型推荐关系式。
Drift flux model is prevailing for the prediction of void fraction in two-phase flow, whereas distribution parameter C0 and drift velocity ugj of the model are an issue argued by different researches until now. This subject is experimentally and theoretically studied in the paper and the limiting conditions of distribution parameter and drift velocity for upward two-phase flow are proposed. Finally, the recommended correlation for the void fraction prediction is also presented based on the theoretical analyses and data comparisons.
