要約

This paper presents modelling studies on the problem of evaporation in a horizontal tube. The results of Jung (1989) show a considerable variation of the heat transfer coefficient around the periphery of the tube at low qualities, with the top of the tube having the highest coefficient. It is shown that this region is likely to be one in which slug flow occurs and this situation is analysed both from a hydrodynamic and from a heat transfer point of view. The transition into the low quality regime is shown to be closely associated with lhal into slug flow, using an existing flow pattern map. An analysis of the heat transfer in the slug and inter-slug ("film") regions leads to successful prediction of the heat transfer coefficients at the top and bottom of the tube.
