Sketch of multiphase flow in an oil pipe, where the continuous phase is the liquid (blue) carrying smaller particles. Gas (white) and oil particles (black) are in a disperse phase. In fluid mechanics, multiphase flow is the simultaneous flow of materials with two or more thermodynamic phases. [1] Virtually all processing technologies from

Summary. Chapter 1 provides an overview of the concepts and exemplified applications of multiphase flows. It illustrates the distinctly different transport patterns or phenomena of individual phase in a multiphase flow, which have either naturally caused or intentionally designed consequences. The chapter conveys the basic definitions of a

Introduction. Scope. In the context of this book, the term multiphase flow is used to refer to any fluid flow consisting of more than one phase or component. For brevity and because they are covered in other texts, we exclude those circumstances in which the components are well mixed above the molecular level. Consequently, the flows considered

1.2.1 Mass Balances. The mass of phase i in a volume element V moving with phase i velocity is, $$ {m}_i=\underset {V (t)} {\iiint } {\varepsilon}_i {\rho}_i dV $$. where εi is the volume fraction of phase i, and ρi is defined as the density of phase i. This volume fraction is the only new variable in multiphase flow.

A multiphase flow is a fluid flow consisting of more than one phase component and has some level of phase separation above the molecular level. Multiphase flows exist in many different forms. Two phase flows can be classified according to the state of the different phases: Gas-Liquid mixture. Gas-Solid mixture.

wThere are three ways to measure multiphase flows.5.1 SeparationT. traditional approach to measuring multiphase flow is separation. In the North Sea, three-phase gravity separators are common but else. ere in the world two-phase separators are more likely to be used. Separators work by exploitin.

The expression of multiphase fluid flow might be indicated as "number of phases" + "flow" in accordance with the total number of phases. For instance, the mixture of liquid water and liquid oil can be classed as a two-phase flow or a multiphase flow. On the upshot, multiphase flow is the interaction of more than one matter or phase of

Introduction. The motion of fluids is complex enough when we only consider one "phase" of matter at a time, i.e. a purely liquid or purely gaseous flow. However many problems of practical interest involve liquids and gases simultaneously. This is what we call "multiphase flow", and it is famously difficult both to measure experimentally
