Research output: Contribution to journalArticlepeer-review


This paper gives a comprehensive interpretation on the flow patterns occurring in gas-liquid horizontal, inclined and vertical pipeline flows and investigates various effects on their transitions. The postulated theoretical models for prediction of flow pattern transitions in systems without mass transfer are presented in detail. For horizontal pipe flows with boiling and condensation, a modified mechanistic theory is suggested; the predicted transitions are in good agreement with the experimental data. Finally, the approaches developed by Venkateswarar et al. (1982) to modelling the flow pattern transition for two-phase flows of steam and water in vertical rod bundles are presented.
