Velocity profiles for flow of omani crude oils and other liquids

الملخص EN

Velocity profiles of Newtonian immiscible liquids undergoing laminar flow between two horizontal plates under pressure gradient are investigated using a momentum balance equation.

The differential equation describing the flow has been solved and equations for the velocity profiles of a two-layer and three-layer liquid systems are presented.

As examples, we show flow patterns of two-layer water-crude oil system and three-layer system involving water, tetrachloromethane, xylene, cyclopentane and hexane.

A distinctive pattern is noticeable between the velocity profiles of heavy (API 19.19) and light (API 40.89) Omani crude oils.
