Oil-water annular two-phase flow in horizontal pipe

Abstract EN

The objective of this work is to gain insight into liquid-liquid annular flow, twocomponent Iraqi gasoil-water flow lengths in horizontal circular transparent pipe of 32mm inner diameter and 6m length, experiments done at atmospheric condition with oil and water as the working fluids.

The flow patterns that appear are classified in flow pattern maps as functions of either mixture velocity and water cut or superficial velocities.

The superficial water velocity ranged from 1.69 m/s to 3.38 m/s with superficial oil velocity around 0.39 m/s to 1.58 m/s.

The effects of superficial water velocity, superficial oil velocity on annular flow lengths were taken into account.

However, the essentials of the problem involve the determination of the pressure gradient.

In this experimental work a video camera "high speed camera" system with image processing technique by MATLAB were used to extract the hold up for the fluid that being the annular flow.

The theoretical study was executed using fluent program, a modified turbulent diffusion model is adopted.

Simulation results show more physical predictions with respect to the particle deposition process and concentration profile.

New data for hold up lengths were found which achieved good agreements with the previous works.
