本文讨论了水平管道两相流的相似问题。根据两相流的能量方程、连续性方程及颗粒悬浮条件等关系,得出水平管道两相流的相似条件为 C_v~2/(C_gC_l)=1;C_λC_l/C_D=1;C_ζ=1; C_(γ_(T~γ))/γ_TC_mC_nC_w/C_v=1;(C_(γ_(T~γ)))/γ_TC_mC_(1-n)C_f=1; C_v/C_w=1;C_Q/(C_D~2C_v)=1. 根据这些条件,提出了管道两相流模型试验的计算原则,最后,以已有的实验资料对上述计算原则进行了校验。本文还根据悬浮附加损失及推移附加损失的相似条件,提出了两个新的相似准数:Fu及Tu。
This article discusses the similarities of horizontal two-phase flow pipelines. According to the energy equation, continuity equation and particle suspension condition of two-phase flow, the similar conditions of two-phase flow in horizontal pipe are obtained as C_v ~ 2 / (C_gC_l) = 1; C_λC_l / C_D = 1; C_ζ = 1; C_ (γ_ (T~γ)) / γ_TC_mC_nC_w / C_v = 1; (C_ (γ_ (T~γ))) / γ_TC_mC_ (1-n) C_f = 1; C_v / C_w = 1; C_Q / (C_D ~ 2C_v) = 1. According to these conditions, the calculation principle of pipeline two-phase flow model test is proposed. Finally, the above calculation principle is verified by the existing experimental data. In this paper, two new similar standards are proposed according to the similar conditions of additional surcharges and additional losses: Fu and Tu.
