Hydrodynamics of ascending film flow and critical regions of heat transfer in circular channels of thermosiphons with steam-generating circuit

The work covers investigation of mechanism of interrelationship between critical region of flow and heat transfer in circular channels of thermosiphons, determination of their ultimate heat transfer capability. A method of a liquid film thickness measurement has been developed. A chart of flow condition in vertical circular channels has been plotted. Mechanism of critical regions of flow influence on critical regions of heat transfer in circular channels of thermosiphons has been studied. Empirical relations have been offered for designing ultimate heat transfer capability of thermosiphons with internal circulation inserts. Designing accuracy of ultimate heat transfer capability of thermosiphons with internal inserts has been improved.
