ABSTRACT
The results of an experimental research of the structure of an adiabatic two-phase (air-water) flow in tubes with a twisted tape insert at p = 0.1−0.15 MPa are presented. The slug, wave, annular, disperse, and cord regimes have been revealed. The main feature of the structure in such channels is that a liquid-phase part (and all liquid at the high range of gas qualities) moves in the form of a stream (a cord) on the tape and does not contact an active heat transfer surface. The device for intensification of heat and mass transfer (especially at boiling) in the form of the twisted tape with ribs discretely installed on an angle to a tape axis is offered. The ribs on the tape promote displacement ofa liquid from the tape to a tube heat transfer surface. The results of an experimental research of a heat transfer and a hydraulic resistance in tubes with various tape twisting inserts also are presented. The possibility of an effective utilization of the twisted tapes with ribs for an intensification of a heat and mass transfer in tubes is shown.
