From Wikipedia, the free encyclopedia
In fluid mechanics, multiphase flow is the simultaneous flow of materials with two or more phases. These phases may consist of one chemical component (e.g. flow of water and water vapor), or several different chemical components (e.g. flow of oil and water). [1] A phase is classified as continuous if it occupies a continually connected region of space. Whereas a classification of disperse is applied when the phase occupies disconnected regions of space. The continuous phase may be either gaseous or a liquid. The disperse phase can consist of either a solid, liquid or gas.[2]

Two general topologies can be identified, disperse flows and seperated flows.The former being those consisting of finite particles, drops or bubbles distributed within a continuous phase. The latter is defined as consisting of two or more continuous streams of fluids separated by interfaces.[3]
