Hydrodynamics of viscous oil water flow through undulated pipelines

Abstract

The flow of two immiscible liquids occurs commonly in petroleum industry where crude oil and water produced from wells are transported over long distances for subsequent separation and processing In such cases undulation of pipelines comprising of interconnected horizontal upward and downward inclined sections are inevitable due to different elevation of the earth surface Therefore it is necessary to understand the different flow patterns and their transition boundaries for proper designi
