Phase Phase refer to liquid,solid,and vapor state of material 。 Multiphase flow means a flow of a mixture of phases,ignoring the well mixed flow above the molecular level ·Classification: state of different phase:solid-gas flow Application slurry flow,aerosols A specific type:low Reynold suspension flow Multiphase flow phenomena is everywhere: Industrial application - Nature world,biological and medical fluid Dispersed phase flow and separated phase flow Dispersed phase flow means one continuous phase containing a discrete phase,such as rain droplet in air. Separated phase flow means two phases are separated by a well-defined surface(interface), such as river surface. In a separated phase flow,one can travel from one point to another in/through the same phasePhase • Phase refer to liquid, solid,and vapor state of material • Multiphase flow means a flow of a mixture of phases, ignoring the well mixed flow above the molecular level • Classification : – state of different phase: solid-gas flow – Application :slurry flow, aerosols – A specific type: low Reynold suspension flow • Multiphase flow phenomena is everywhere: – Industrial application – Nature world, biological and medical fluid • Dispersed phase flow and separated phase flow – Dispersed phase flow means one continuous phase containing a discrete phase, such as rain droplet in air. – Separated phase flow means two phases are separated by a well-defined surface(interface), such as river surface. – In a separated phase flow, one can travel from one point to another in/through the same phase
