Аннотация

The paper presents the results of an integrated investigation into the important hydrodynamic characteristics of an ascending annular-dispersed steam-liquid flow: the distribution of the liquid between the core and film, the film thickness and surface structure, and pressure drop. The boundaries of existence of the basic patterns of two-phase flows were determined.
The experiments were carried out in an unheated vertical tube with an inside diameter of 13.3 mm in the range of the following pattern parameters: pressure (10−100)×105 N/m2 mass flux density 500−4000 kg/m2·s, and steam quality 0.1−0.9.
