Hydrodynamics of viscous oil-water flow through horizontal and upward inclined pipelines

The flow of two immiscible liquids through conduits is widely encountered in various fields such as the chemical and petroleum industries. Liquid-liquid two-phase flow has many applications in almost all fields of chemical engineering (such as solvent extraction, emulsification, bio diesel production, etc) and petroleum industry. In the petroleum industry oil is produced and transported along with water to minimize power consumption and pumping cost by reducing frictional pressure drop. Pressure drop is an important parameter in the design of an efficient transportation system, and is greatly affected by characteristics of transportation line and fluid properties. Since last 60 years, several attempts have been made in understanding the science behind the hydrodynamics of liquidliquid flow through pipelines. Past literature shows that most of the available literature for oil-water flow through horizontal or vertical or incline pipes are with either less (0.936- 9.87 m Pa s) or high (300-1300 m Pa s) viscous oil. The past works on oil-water system having the viscosity of intermediate range are very limited, especially in inclined pipeline. Hydrodynamics of intermediate viscous oil-water flow through pipelines is important due to the gradual exhaustion of lighter crude oil. Considering the aforementioned facts, the present study aims at the investigation of hydrodynamics of viscous oil-water (intermediate viscosity range) flow through 5ओ upward inclined pipeline. Prior to this, studies have been focused on the hydrodynamics of such flow through horizontal pipeline for the comparison and better understanding of the physics behind the flow phenomena.
