ANALYSIS OF HORIZONTAL AIR-SILICONE OIL PLUG-TO-SLUG TRANSITION FLOW
Abstract:
Understanding the flow behavior during the transition from plug to slug flow is crucial in various industrial applications, particularly in multiphase flow systems. This study focuses on the analysis of horizontal air-silicone oil plug-to-slug transition flow, aiming to provide insights into the hydrodynamic characteristics and mechanisms underlying the transition process.
The experimental investigation involved the use of a horizontal test section, where air and silicone oil were used as the gas and liquid phases, respectively. The flow patterns were visualized and recorded using high-speed imaging techniques, allowing for detailed analysis of the transition from plug to slug flow.
The analysis focused on several key aspects, including the flow regime transition criteria, slug length and frequency, pressure drop, and liquid holdup. The effects of various operating parameters, such as gas and liquid velocities, pipe diameter, and physical properties of the fluids, were also investigated.
The results revealed that the transition from plug to slug flow was influenced by the superficial velocities of both the gas and liquid phases. As the gas velocity increased, the transition occurred at lower liquid velocities. The slug length and frequency were found to be dependent on the gas and liquid flow rates, with higher velocities resulting in shorter and more frequent slugs. The pressure drop and liquid holdup were also observed to vary significantly during the transition process.
Furthermore, the study provided insights into the mechanisms governing the plug-to-slug transition, including interfacial shear forces, capillary pressure, and liquid film dynamics. The findings contribute to a better understanding of the complex flow behavior during the transition and can be valuable for optimizing the design and operation of multiphase flow systems.
In conclusion, this analysis of horizontal air-silicone oil plug-to-slug transition flow enhances our understanding of the hydrodynamic characteristics and mechanisms involved in this complex flow regime. The findings can be applied to various industrial processes, including oil and gas transportation, chemical processing, and nuclear reactor cooling systems, thereby improving their efficiency and reliability. Further research is warranted to explore additional factors influencing the transition process and to validate the findings under different experimental conditions.
