Abstract
Dryout of counter-current two-phase flow is widely observed in the actual chemical and/or industrial systems. In case of the diabatic counter-current two-phase flow, the upward gas increases with the liquid film evaporation along the heating tube and flooding strongly affects the dryout of counter-current two-phase flow. In this investigation, the dryout experiment was conducted with the counter-current two-phase flow consisted of the free falling liquid film and upward gas flow. The obtained dryout characteristics were strongly influenced by the degree of inlet subcoooling, and are classified into three groups on the basis of the dryout mechanism.
