Abstract

Two-phase flow of gas/non-Newtonian fluid through pipes is commonly occurred in chemical industry and oil and gas refinery. Many correlations have been developed to evaluate pressure drop for non-Newtonian fluids. Based on that, these systems are not governed by Newtonian law of viscosity. However, only little experimental work has been devoted to study non-Newtonian flow behavior. In this present work, experimental setup has been conducted to investigate non-Newtonian two-phase (gas/ liquid) flow through pipes. Several concentrations of Xanthan Gum have been used as non-Newtonian liquid in the experiments and compressed air has been used as a gas. The flow rate and pressure of liquid and gas are changed by using a pump placed ahead of the mixing point. Pressure and temperature values are recorded by pressure sensors and thermocouples fixed at specific points along the pipe loop. Results of theses experiments are leaded to come up with experimental model for pressure drop of gas/non-Newtonian flow in pipes. Moreover, the flow regimes of two-phase gas/non-Newtonian flow at different conditions have been visualized through transparent tubes using a high-speed camera.
水平管内气体/非牛顿流压降的实验研究
气体/非牛顿流体在管道中的两相流动在化工和石油、天然气炼化中是常见的。已经开发了许多关系式来评估非牛顿流体的压降。基于此,这些系统不受牛顿粘度定律的约束。然而,研究非牛顿流体流动特性的实验工作很少。在目前的工作中,进行了实验装置来研究非牛顿两相(气/液)通过管道的流动。在实验中,几种浓度的黄原胶被用作非牛顿液体,压缩空气被用作气体。通过在混合点前面放置一个泵来改变液体和气体的流速和压力。压力和温度值由固定在管道回路特定点的压力传感器和热电偶记录。根据实验结果,建立了管道内气体/非牛顿流压降的实验模型。此外,在不同条件下,两相气体/非牛顿流的流动形式已通过透明管使用高速摄像机可视化。
