摘要: 本文依据文献[1]的密相两相流动的数学模型,对垂直圆管中密相两相流动进行了解析求解,分别得到了连续相和分散相的速度解析表达式.在相间阻力与相间速度差成比例时,除了在离管壁面很近的薄区之外,管道流动规律与达西渗流定律完全一致.本文验证了文献[1]的密相两相流动数学模型的假定在本文情形下是合理的.

Abstract: According to a mathematical model for dense two-phase flows presented in the previous pape^[1],a dense two-phase flow in a vertical pipeline is analytically solved,and the analytic expressions of velocity of each continuous phase and dispersed phase are respectively derived.The results show that when the drag force between two phases depends linearly on their relative velocity,the relative velocity profile in the pipeline coincides with Darcy's law except for the thin layer region near the pipeline wall,and that the theoretical assumptions in the dense two-phase flow theory mentioned are reasonable.
