| 摘 要： | 对基于微重力条件下,气／液两相弹状流滑移流率关系和光滑环状流动量平衡关系的弹-环状流转换空隙率匹配模型的解的特征,进行了深入分析．发现该模型具有双解、单解和无解三种情况．由此阐明了该模型难以正确预测微重力条件下气／液两相弹-环．状流转换条件的原因在于光滑环状流动量平衡关系的非客观性．

| Abstract: | A detailed analysis on the characteristics of the solution of the void fraction matched model for the slug to annular flow pattern transition at microgravity condition, which is based upon the drift flux raletionship of slug flow and the momentum balance relationship of smooth annular flow, is presented. It is found that the number of the solutions of this model may be 2, 1, or zero. It is pointed that the failure of this model in predicting the transition stems from the non objective of the momentum balance relationship of smooth annular flow. |
