Numerical simulations for turbulent oil-water core-annular flow

The transportation of high viscosity oil is an ongoing research topic for quite some years because of its importance in industrial applications and the increasing energy requirements of the world population. The water lubricated oil core with a core-annular flow configuration is a viable option for the transport of high viscosity oil. It was...

Interface Investigation of Core-annular Flow

The transport of highly-viscous oil in the core-annular flow regime in a horizontal pipe is investigated with a numerical simulation study. In this flow type the viscous oil is lubricated by a water annulus along the pipe wall. The Launder-Sharma low-Reynolds number k-ε turbulence model is used with the Volume-of-Fluid solver in interFOAM. Three...

Influence of oil viscosity on oil-water core-annular flow through a horizontal pipe

Transportation of very viscous fluids through pipelines is a real challenge. With the depletion of light oils in reservoirs, it becomes economically favourable to harvest heavy crude oils to contribute to meeting the ever growing energy demand. A suitable candidate for the transportation of these very viscous oil is by means of core-annular flow...
