Abstract:Theories and methods used in flow regime identifications at room temperature are introduced in the present work. Their applicability at cryogenic temperature is also discussed. Some instruments used in flow regime identifications at cryogenic temperature are introduced. It is pointed out that the researches and measurements on cryogenic flow regime identifications are anything but perfect, methods based on physical mechanisms should be developed.
Keywords:Cryogen  Gas-liquid two-phase flows  Flow regime identification  Measurements  Physical mechanisms
