建模通过旋转两相流管与双出口分支

文摘

提出了一种数值模型的动态行为单相和两相的双组分流经水平旋转和同卵双胞胎退出分支管。工作流体、石油、进入管通过径向管一端连接并通过双径向出口到露天分支,最后一个位于中途,另一管。branch-to-tube直径比、转速和总石油流量是多种多样的。实验显示在先前的研究中,空气空化发生在较低的速度,导致两相流的床比(空隙率)不同转速。一个独特的特性在两相流,即。,hysteresis, is found to exist in both oil flow rates and inlet pressure. In theoretical modeling, the governing flow equations are incorporated by empirical equations for hydraulic head losses. The predicted and measured exit oil flow rates are compared with good agreement in both the single-phase and annular flow regimes. Only qualitative agreement is achieved in the bubbly and bubbly-slug flow regimes. The model can be applied to improve the design and thus enhance the performance of automatic transmission lines, and the cooling efficiency of rotating machines and petroleum drilling process.
