Chapter 18. Introduction to ModelingMultiphase FlowsA large number of flows encountered in nature and technology are a mix-ture of phases. Physical phases of matter are gas, liquid, and solid, butthe concept of phase in a Multiphase flow system is applied in a broadersense. In Multiphase flow, a phase can be de ned as an identi able classof material that has a particular inertial response to and interaction withthe flow and the potential eld in which it is immersed. For example,di erent-sized solid particles of the same material can be treated as dif-ferent phases because each collection of particles with the same size willhave a similar dynamical response to the flow Chapter provides an overview of Multiphase Modeling inFLUENT,and Chapters 19 and 20 provide details about the Multiphase modelsmentioned here. Chapter 21 provides information about melting andsolidi in this Chapter is presented in the following sections: Section : Multiphase Flow Regimes Section : Examples of Multiphase Systems Section : Approaches to Multiphase Modeling Section : Choosing a Multiphase Modelc Fluent Inc.
