| 摘 要： | 在日本原子力研究所的一个两以试验台架上,进行了环形流道空气－水丙相流窟泡份额和逆向流试验,观察了其流型。通过试验和分析,提出了漂移流模型中分布系数Co和气相漂移速度Vgi的经验关系式;得到了逆向流Wallis表达式的拟合参数。对试验结果的分析表明,当流道间隙很小（Bond数小于1）时,流型和两相流动与间隙较大时有所不同。

| Abstract: | Air-water two-phase flow void fraction and counter-current experiments in annular channel are performed in a two-phase flow test loop at Japan Atomic Energy Research Institute,flow structure is also observed.The distribution coefficient Co and drift velocity Vg j correlations for the flux flow model are proposed,the coefficients for Wallis correlation are obtained by data fitting.According to the analysis of experiment data,it is found that the flow structure and two-phase flow in narrow annular channel (Bond Number <1) showed some different phenomena from those in large gap annular channel. |
