基于分相流模型的三相流管道压降计算

Tri-phase Flow Pressure Drop in Pipeline Based On Separating Flow Pattern

以气液两相流为基础 ,依据稳定一维均流流动的基本方程推导出了三相流管道输送分相流模型的压降计算式 ,并给出了水平管的压降计算实例 ,总结出了气相含量与压降的关系 。

Based on the theory of gas liquid two liquid flow and the primary equations of single dimension invariable fluid, the pressure drop calculating equation of tri phase flow about separating flow pattern is deduced from. The calculation instance has been given based on the pattern in a horizontal pipeline.The relationship between gas content and pipeline's pressure drop is summed up and it concludes that air has little effect on pressure drop in tri phase flow pipeline.
