摘要：
A quasi-one-dimensional hydrodynamic model of gas-vapor-liquid dispersed-annular flows in a round tube is considered which takes account of all the main features of these flows (dissimilar velocities and temperatures of phases, the occurrence of heat and mass transfer processes between phases). The results of experimental studies on the determination of forced interaction and rates of moisture exchange between the flow core and liquid film are analyzed. Examples of a numerical experiment on the determination of pressure drop, liquid distribution between the flow core and the film as well as burnout heat transfer under steady- and unsteady-stage conditions are presented.
